How to turn on https-only mode in mozilla firefox

How do I disable HTTPS redirect. I am “aware of the risks” blah blah paranoid blah. And well aware of what I’m doing. But for some reason with 32 no everything heads over to https including non-https bookmarks.

No matter how I type it in; HTTP://www.xxxx www.xxxxx

I would like to find some way, by setting, about:config command (or hack if I have to) or even an extension someone could point me to that could stop this maddening overuse of secure transfers.

Chosen solution

Disabling https, is not an absolute in Firefox. Some sites will redirect and may not offer http.

However to choose one url over the other if it is an option you can disable autofil:

Address Bar Search In order to change your Firefox Configuration please do the following steps :

  1. In the Location bar, type about:config and press Enter. The about:config “This might void your warranty!” warning page may appear.
  2. Click I’ll be careful, I promise! to continue to the about:config page.
  3. In the filter box, type or paste autofill and pause while the list is filtered
  4. Double-click browser.urlbar.autoFill to toggle it from true to false.

It’s not all sites, though, just some sites? Like the following URL that you’ve never visited before (on a site that has not SSL support):

If ALL sites attempt HTTPS, make sure you haven’t installed the “HTTPS Everywhere” extension or something similar.

You can review and disable extensions on the Add-ons page. Either:

  • Ctrl+Shift+a
  • “3-bar” menu button (or Tools menu) > Add-ons

In the left column, click Extensions. I suggest disabling unrecognized and nonessential extensions, and removing any that obviously are undesirable (if any).

Often a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.

Starting in Firefox version 83, you can change your preferences to HTTPS-Only Mode. This security enhancing mode forces all connections to websites to use HTTPS. Most websites already support HTTPS; some support both HTTP and HTTPS. Enabling this mode provides a guarantee that all of your connections to websites are upgraded to use HTTPS and hence secure. Learn more about the benefits and how to enable HTTPS-Only Mode.

HTTP stands for Hypertext Transfer Protocol and is the foundational protocol for the web and encodes basic interactions between browsers and web servers. The problem with the regular HTTP protocol is that the data transferring from server to browser is not encrypted, meaning data can be viewed, stolen, or altered. HTTPS protocols fix this by using an SSL (secure sockets layer) certificate, this creates a secure encrypted connection between the server and the browser which protects sensitive information.

When you use HTTPS-Only Mode, this ensures all of your connections are encrypted and secure. So you have peace of mind that no one can snoop on the content of the pages you visit or hack into your connection to a website to steal your passwords, credit card information, or other personal information. This is especially useful when you are using a public WiFi where you can’t be sure of the integrity of your internet connection.

For example when HTTPS-Only Mode is active and a site is visited such as http://example.com , Firefox will silently upgrade to https://example.com :

Enable/Disable HTTPS-Only Mode

In the Menu bar at the top of the screen, click Firefox and select Preferences . Click the menu button and select Options Preferences . Click the menu button and select Settings .

Some websites only support HTTP and the connection cannot be upgraded. If HTTPS-Only Mode is enabled and a HTTPS version of a site is not available, you will see a “Secure Connection Not Available” page:

If you click Continue to HTTP Site you accept the risk and then will visit a HTTP version of the site. HTTPS-Only Mode will be turned off temporarily for that site.

Click the Go Back button if you want to avoid any unencrypted connections.

If HTTPS-Only Mode is enabled and you frequently visit a website that does not support HTTPS or does not seem to be rendering certain elements of the page correctly, you can turn off HTTPS-Only Mode for a particular site.

  1. Click on the Lock icon in the address bar.
  2. Use the dropdown under HTTPS-Only Mode and select Off . How to turn on https-only mode in mozilla firefox

If a website isn’t displaying correctly and it’s one you trust and want to visit, you can turn off HTTPS-Only Mode for that site. Exceptions allow you to visit an HTTP version of a website while you’re browsing in HTTPS-Only Mode. Exceptions can be applied temporarily for a single browsing session, or permanently. To add an exception for a website:

In the Menu bar at the top of the screen, click Firefox and select Preferences . Click the menu button and select Options Preferences . Click the menu button and select Settings .

Mozilla Firefox’s HTTPS-Only Mode provides extra privacy and security online. With it enabled, Firefox will try hard to only load encrypted HTTPS websites. If only HTTP is available, Firefox won’t load the unencrypted website without asking you.

Why Is HTTPS Important?

The secure protocol HTTPS is the bedrock method of maintaining privacy and security on the web. It sets up an encrypted connection between your browser and the web server that prevents third parties from eavesdropping on or tampering with the data being sent between you and the site you’re browsing.

Unfortunately, not all sites support HTTPS, and some that do may fall back to non-encrypted HTTP versions of a site if you visit them through an HTTP link (such as http://www.example.com instead of https://www.example.com notice the missing “s” in the address).

Starting in Mozilla Firefox version 83, which was released on November 16, 2020, you can turn on HTTPS-Only Mode. Firefox will automatically attempt to load the HTTPS version of a website even if you visit the site through a link to an unencrypted HTTP address. If one isn’t available, you’ll have to provide explicit permission before Firefox will load an HTTP page. Here’s how to enable this option.

How to Enable HTTPS-Only Mode in Firefox

First, open Firefox and click the hamburger button (three horizontal lines) in any Firefox window. In the menu that pops up, select “Options” on Windows and Linux or “Preferences” on a Mac.

Tip: If you’re not running Firefox version 83 or higher, you’ll need to update Firefox to use the HTTPS-Only Mode feature. To check for updates manually, click the Firefox menu, then select Help > About Firefox. Then click the “Update Firefox” button.

In the “Options” or “Preferences” tab, click “Privacy & Security” in the sidebar menu.

On the “Browser Privacy” preferences page, scroll down to the bottom and locate the “HTTPS-Only Mode” section. Click the radio button beside “Enable HTTPS-Only Mode in all windows” to select it. (You also have the choice to enable HTTPS-Only Mode in private windows only, so select that instead if you prefer.)

After that, close the Options tab, and the change will take effect immediately. If you visit a website through a non-encrypted HTTP link that supports HTTPS, you will be redirected to the encrypted HTTPS version of the site automatically.

What Happens If a Site Doesn’t Support HTTPS?

If you visit a site with HTTPS-Only Mode turned on and the site does not support HTTPS, you will see an error page similar to this one.

Also, if you visit a site that is only partially HTTPS-secure that is, it pulls non-encrypted elements into the secure page it may not display properly with HTTPS-Only Mode enabled.

In either case, Mozilla has provided a quick way to temporarily disable HTTPS-Only Mode. To do so, click the lock icon beside the website address in the URL bar.

In the menu that pops up, click the drop-down menu below “HTTPS-Only Mode” and choose “Off temporarily” to temporarily disable HTTPS-Only Mode.

Alternately, if you’d like to permanently disable HTTPS-Only Mode just for this particular site, select “Off” from the list. Firefox will remember these settings individually for each website.

After that, you’ll be able to see the site as usual. If the site ever upgrades to support HTTPS fully, you can enable HTTPS-Only Mode for the site again using the same menu option hidden under the web address lock icon. Happy browsing!

Web browsers like Mozilla Firefox and Google Chrome are encouraging websites to move away from HTTP to more secure HTTPS connections. It’s likely that Firefox’s HTTPS-Only Mode will one day become the default option, boosting privacy and security online—and further encouraging website owners to upgrade to HTTPS.

When choosing one web browser or another, we take into account a multitude of aspects. These can be related to both the functionality and the security or the interface of the program itself. Considering that we have a good number of proposals to choose from, this is easier than ever.

With all this and with this, most users increasingly take into consideration everything related to privacy and security in this type of program. The developers of these are fully aware of all this, which is why more and more solutions of this type are available to us. In this way, the functionalities related to taking care of our privacy and security are increasing.

These come to us as a rule through new updates that are sent periodically to our teams. At the same time, these programs, which serve as a way to connect us to the Internet, have to adapt to the latest trends and technologies on the Internet. And that is precisely what we are going to talk about next, focusing on the browser owned by Mozilla, Firefox.

As we mentioned before, the creators of this type of program take into account the preferences of their millions of clients. Hence, they are increasingly careful to take care of the sections that concern them the most.

What is it and why should I enable Firefox HTTPS Only mode

It is precisely for this reason that now we are going to talk about a functionality that has arrived relatively recently in the Firefox browser. This is known as HTTPS Only mode , an element that helps us improve the experience of using the program. In fact, we could say that, with this mode enabled, Firefox takes care of loading only HTTPS websites encrypted in advance.

To give you an idea, in the event that we activate this functionality , the program will not load an unencrypted website without asking us first. In this way, we largely avoid accessing potentially dangerous websites. Specifically, the secure HTTPS protocol is a very important method to maintain privacy and security on the web. It establishes an encrypted connection between the browser and the web server . In this way, what is avoided is that third parties have the possibility of spying on the data that is sent between our local computer and the web that we are visiting.

Another section that we must take into account is that all sites are compatible with HTTPS at the moment. Therefore, some of these make use of unencrypted HTTP versions of a website when we access it, with the risks that this entails in the times. also for all this, the heads of Firefox opted to make the aforementioned Only HTTPS mode available to us.

How to activate this mode to increase security in the browser

It is interesting to know that this mode we are talking about is going to propose three configuration alternatives to choose from. With the active mode the browser itself will try to automatically load the HTTPS version of a website. The interesting thing about all this is that this step occurs even if we connect to the website in question through an unencrypted HTTP link. Thus, in the event that there is no other option, we will have to give an explicit permission before Firefox loads an HTTP page .

Enable HTTPS Only mode

Well, once we are clear about what this new implemented functionality is about, let’s see how we can make it work in Mozilla’s browser. The first thing we do is go to the main menu of the program. This is found in a button located in the upper right corner of the main window and is represented by three horizontal lines. Now we just have to click on it to click on the option called Settings. This will lead us to the configuration window of the browser itself.

How to turn on https-only mode in mozilla firefox

In it, specifically in the left panel we see a category called Privacy & Security, where we are located. Here we are going to find a good number of configurable and customizable parameters related to these two important aspects of the program. All this will allow us to determine the level of security that we want to do and use in Firefox. At that moment, in the right panel, we scroll down the screen to locate the section called HTTPS-only mode.

It is worth mentioning that by default the program has this functionality disabled. In this way, if we want to benefit from the aforementioned, we will have to activate it ourselves by hand. At this point we only have to opt for one of the two options that allow us to activate this mode that we are talking about.

Configure security feature in Mozilla browser

While the HTTPS Only mode is disabled by default, when activating it we find two options. The first one refers to activating this function for all the windows of the program. However, at the same time we have the possibility that it only starts when we navigate through a private window. It is very likely that most of the time, since we are opting for the first option .

With everything and with it, we have the possibility of using all this that we tell you only when we are browsing in private mode. And there are many users who opt for these windows when they are going to move through certain internet web pages . So this functionality is nothing more than an added plus to improve this section. Regardless of the option we have chosen, we also have the possibility of managing a series of exceptions in the function.

With this, what we want to tell you is that we have the possibility of indicating to Firefox a series of web pages in which we do not want this mode to start working. This is usually used in certain somewhat special websites that we know in advance are safe even using HTTP . As we can see and in a simple way, thanks to this mode implemented by Mozilla, we can increase security when using our browser in a few seconds. In the event that it becomes more of a nuisance than a positive measure, we can always deactivate it again if we wish.

Newer versions of Mozilla Firefox web browser (version 83.0 and later) come with a new option “HTTPS-Only Mode” in Firefox Preferences or Options window. In this tutorial, we’ll tell you what is the use of this new feature and how to use it.

When you type a website URL in Firefox web browser, you might have noticed the HTTP or HTTPS words at the beginning of the URL in the addressbar. HTTP and HTTPS are actually names of protocols which create connection between your web browser and the website server. HTTP (Hypertext Transfer Protocol) is an old protocol and doesn’t provide much security. The data transferring between your browser and the website server using this protocol can be altered or viewed. On the other hand, HTTPS is an improved and more secure version of this protocol which encrypts the connection between your browser and website using SSL (Secure Sockets Layer).

It’s always advised to visit websites which use HTTPS protocol for the connection. Almost all websites including bank, organizations, etc use HTTPS protocol for secure encrypted connection.

A few months back, we told you about a hidden secret preference/flag introduced in Firefox 76.0 and later versions which could be used to force Firefox to always use HTTPS protocol to connect to websites. You can check the tutorial at following link:

This new feature is called HTTPS-only mode which forces Firefox to always upgrade connections to all websites to secure HTTPS protocol. If a website uses HTTP connection, Firefox will upgrade the connection to HTTPS. If the website doesn’t support HTTPS protocol, you’ll get “Secure connection not available” error page. You’ll still get a button “Continue to HTTP Site” to visit the website using less secure HTTP protocol.

In past, users had to modify a secret preference/flag using Firefox advanced configuration page ( about:config ) to activate and enable this new feature.

Now Mozilla has added a UI for this option to direct control this hidden secret feature. You can access the UI option in Firefox Preferences in newer versions of Firefox (version 83.0 and later).

If you also want to apply and activate HTTPS-Only Mode in Mozilla Firefox web browser for improved security, following steps will help you:

1. Open Firefox and click on the Hamburger icon present at the right-side end of the toolbar to open the main menu. Now click on Options menu to open Firefox settings page.

Alternatively, you can direct option this page using about:preferences command in address bar.

2. Now under “Privacy & Security” tab, scroll down to bottom and you’ll see “HTTPS-Only Mode” section.

3. To enable and activate HTTPS-only mode in Firefox, select “Enable HTTPS-Only Mode in all windows” option.

If you want to enable HTTPS-Only Mode in private or incognito windows only, select “Enable HTTPS-Only Mode in private windows only” option.

If you want to disable HTTPS-Only Mode, select “Don’t enable HTTPS-Only Mode” option.

PS: The previous preferences/flags in about:config page to control this new HTTPS-Only mode still work. Advanced users can still modify those flags to modify HTTPS-Only mode in Firefox. You can set the flags to True or False to enable or disable HTTPS-Only mode feature. For your convenience, we are sharing the flags here:

  • dom.security.https_only_mode (to enable HTTPS-Only mode in all windows)
  • dom.security.https_only_mode_pbm (to enable HTTPS-Only mode in private windows only)

BONUS TIP:

After enabling HTTPS-Only Mode, if you found a website not supporting HTTPS-Only mode and you frequently visit that website, you can disable or turn off HTTPS-Only mode for that website by clicking on Lock icon showing in the address bar and selecting OFF option given in HTTPS-Only Mode drop-down box.

Security on the web matters. Whenever you connect to a web page and enter a password, a credit card number, or other sensitive information, you want to be sure that this information is kept secure. Whether you are writing a personal email or reading a page on a medical condition, you don’t want that information leaked to eavesdroppers on the network who have no business prying into your personal communications.

That’s why Mozilla is pleased to introduce HTTPS-Only Mode, a brand-new security feature available in Firefox 83. When you enable HTTPS-Only Mode:

  • Firefox attempts to establish fully secure connections to every website, and
  • Firefox asks for your permission before connecting to a website that doesn’t support secure connections.

How HTTPS-Only Mode works

The Hypertext Transfer Protocol (HTTP) is a fundamental protocol through which web browsers and websites communicate. However, data transferred by the regular HTTP protocol is unprotected and transferred in cleartext, such that attackers are able to view, steal, or even tamper with the transmitted data. HTTP over TLS (HTTPS) fixes this security shortcoming by creating a secure and encrypted connection between your browser and the website you’re visiting. You know a website is using HTTPS when you see the lock icon in the address bar:

How to turn on https-only mode in mozilla firefox

The majority of websites already support HTTPS, and those that don’t are increasingly uncommon. Regrettably, websites often fall back to using the insecure and outdated HTTP protocol. Additionally, the web contains millions of legacy HTTP links that point to insecure versions of websites. When you click on such a link, browsers traditionally connect to the website using the insecure HTTP protocol.

In light of the very high availability of HTTPS, we believe that it is time to let our users choose to always use HTTPS. That’s why we have created HTTPS-Only Mode, which ensures that Firefox doesn’t make any insecure connections without your permission. When you enable HTTPS-Only Mode, Firefox tries to establish a fully secure connection to the website you are visiting.

Whether you click on an HTTP link, or you manually enter an HTTP address, Firefox will use HTTPS instead. Here’s what that upgrade looks like:

How to turn on HTTPS-Only Mode

If you are eager to try this new security enhancing feature, enabling HTTPS-Only Mode is simple:

  1. Click on Firefox’s menu button and choose “Preferences”.
  2. Select “Privacy & Security” and scroll down to the section “HTTPS-Only Mode”.
  3. Choose “Enable HTTPS-Only Mode in all windows”.

Once HTTPS-Only Mode is turned on, you can browse the web as you always do, with confidence that Firefox will upgrade web connections to be secure whenever possible, and keep you safe by default. For the small number of websites that don’t yet support HTTPS, Firefox will display an error message that explains the security risk and asks you whether or not you want to connect to the website using HTTP. Here’s what the error message looks like:

How to turn on https-only mode in mozilla firefox

It also can happen, rarely, that a website itself is available over HTTPS but resources within the website, such as images or videos, are not available over HTTPS. Consequently, some web pages may not look right or might malfunction. In that case, you can temporarily disable HTTPS-Only Mode for that site by clicking the lock icon in the address bar:

The future of the web is HTTPS-Only

Once HTTPS becomes even more widely supported by websites than it is today, we expect it will be possible for web browsers to deprecate HTTP connections and require HTTPS for all websites. In summary, HTTPS-Only Mode is the future of web browsing!

We are grateful to many Mozillians for making HTTPS-Only Mode possible, including but not limited to the work of Meridel Walkington, Eric Pang, Martin Thomson, Steven Englehardt, Alice Fleischmann, Angela Lazar, Mikal Lewis, Wennie Leung, Frederik Braun, Tom Ritter, June Wilde, Sebastian Streich, Daniel Veditz, Prangya Basu, Dragana Damjanovic, Valentin Gosu, Chris Lonnen, Andrew Overholt, and Selena Deckelmann. We also want to acknowledge the work of our friends at the EFF, who pioneered a similar approach in HTTPS Everywhere’s EASE Mode. It’s a privilege to work with people who are passionate about building the web we want: free, independent and secure.

When you enable DNS over HTTPS this way, Firefox will use the Cloudflare DNS by default. You can change your DNS by clicking the “Use Provider” drop-down menu and clicking either “NextDNS” to use Mozilla’s chosen alternative, or “Custom” to input your DNS server address of choice manually. However, DNS over HTTPS will only work if your selected DNS server has enabled support for it. You can’t just use any old DNS server.

Even if you don’t enable DoH manually, Firefox will automatically enable it for you over the next few weeks—assuming you’re in the U.S. We expect Mozilla will automatically enable DoH for people in other countries in the future, too.

Lors du choix d’un navigateur Web ou d’un autre, nous prenons en compte une multitude d’aspects. Ceux-ci peuvent être liés à la fois à la fonctionnalité et à la sécurité ou l’interface du programme lui-même. Considérant que nous avons un bon nombre de propositions parmi lesquelles choisir, c’est plus facile que jamais.

Avec tout cela et avec cela, la plupart des utilisateurs prennent de plus en plus en considération tout ce qui concerne la confidentialité et la sécurité dans ce type de programme. Les développeurs de ceux-ci sont parfaitement conscients de tout cela, c’est pourquoi de plus en plus de solutions de ce type s’offrent à nous. Ainsi, les fonctionnalités liées à la prise en charge de nos la vie privée et la sécurité sont en augmentation.

Celles-ci nous parviennent en règle générale via de nouvelles mises à jour qui sont envoyées périodiquement à nos équipes. Dans le même temps, ces programmes, qui servent à nous connecter à Internet, doivent s’adapter aux dernières tendances et technologies sur Internet. Et c’est précisément de cela dont nous allons parler ensuite, en nous concentrant sur les navigateur propriété de Mozilla, Firefox.

Comme nous l’avons mentionné précédemment, les créateurs de ce type de programme prennent en compte les préférences de leurs millions de clients. Par conséquent, ils sont de plus en plus attentifs à s’occuper des sections qui les concernent le plus.

Qu’est-ce que c’est et pourquoi devrais-je activer le mode Firefox HTTPS uniquement

C’est précisément pour cette raison que nous allons maintenant parler d’une fonctionnalité arrivée relativement récemment dans le navigateur Firefox. Ceci est connu comme Mode HTTPS uniquement , un élément qui nous aide à améliorer l’expérience d’utilisation du programme. En fait, on pourrait dire qu’avec ce mode activé, Firefox se charge de charger uniquement les sites Web HTTPS cryptés au préalable.

Pour vous donner une idée, dans le cas où nous activions ce , le programme ne chargera pas un site Web non crypté sans nous le demander au préalable. De cette façon, nous évitons largement d’accéder à des sites Web potentiellement dangereux. Plus précisément, le protocole sécurisé HTTPS est une méthode très importante pour maintenir la confidentialité et la sécurité sur le Web. Il établit une connexion cryptée entre le navigateur et le le serveur web . De cette façon, ce qui est évité, c’est que des tiers aient la possibilité d’espionner les données qui sont envoyées entre notre ordinateur local et le Web que nous visitons.

Une autre section que nous devons prendre en compte est que tous les sites sont actuellement compatibles avec HTTPS. Par conséquent, certains d’entre eux utilisent des versions HTTP non cryptées d’un site Web lorsque nous y accédons, avec les risques que cela comporte dans le temps. aussi pour tout cela, les responsables de Firefox ont choisi de mettre à notre disposition le mode Uniquement HTTPS susmentionné.

Comment activer ce mode pour augmenter la sécurité dans le navigateur

Il est intéressant de savoir que ce mode dont nous parlons va proposer trois alternatives de configuration au choix. Avec le mode actif, le navigateur lui-même essaiera de charger automatiquement la version HTTPS d’un site Web. La chose intéressante à propos de tout cela est que cette étape se produit même si nous nous connectons au site Web en question via un code non crypté. Lien HTTP. Ainsi, dans le cas où il n’y a pas d’autre option, nous devrons donner une autorisation explicite avant que Firefox ne charge un page HTTP .

Activer le mode HTTPS uniquement

Eh bien, une fois que nous saurons clairement en quoi consiste cette nouvelle fonctionnalité implémentée, voyons comment nous pouvons la faire fonctionner dans le navigateur de Mozilla. La première chose que nous faisons est d’aller dans le menu principal du programme. Celui-ci se trouve dans un bouton situé dans le coin supérieur droit de la fenêtre principale et est représenté par trois lignes horizontales. Il ne nous reste plus qu’à cliquer dessus pour cliquer sur l’option appelée Paramètres. Cela nous mènera à la fenêtre de configuration du navigateur lui-même.

How to turn on https-only mode in mozilla firefox

Dans celui-ci, spécifiquement dans le panneau de gauche, nous voyons une catégorie appelée Confidentialité & Sécurité, où nous sommes situés. Ici, nous allons trouver un bon nombre de paramètres configurables et personnalisables liés à ces deux aspects importants du programme. Tout cela nous permettra de déterminer le niveau de sécurité que nous voulons faire et utiliser dans Firefox. À ce moment, dans le panneau de droite, nous faisons défiler l’écran pour localiser la section appelée mode HTTPS uniquement.

Il convient de mentionner que par défaut, le programme a cette fonctionnalité désactivée. De cette façon, si nous voulons bénéficier de ce qui précède, nous devrons l’activer nous-mêmes à la main. À ce stade, nous n’avons qu’à opter pour l’une des deux options qui nous permettent d’activer ce mode dont nous parlons.

Configurer la fonction de sécurité dans le navigateur Mozilla

Alors que le mode HTTPS uniquement est désactivé par défaut, lors de son activation, nous trouvons deux options. La première concerne l’activation de cette fonction pour toutes les fenêtres du programme. Cependant, en même temps, nous avons la possibilité qu’il ne démarre que lorsque nous naviguons dans une fenêtre privée. Il est fort probable que la plupart du temps, puisque nous optons pour le premier option .

Avec tout et avec lui, nous avons la possibilité d’utiliser tout cela que nous vous disons uniquement lorsque nous naviguons en mode privé. Et il y a beaucoup d’utilisateurs qui optent pour ces fenêtres lorsqu’ils vont traverser certains pages internet . Cette fonctionnalité n’est donc rien de plus qu’un plus pour améliorer cette section. Quelle que soit l’option que nous avons choisie, nous avons également la possibilité de gérer une série d’exceptions dans la fonction.

Avec cela, ce que nous voulons vous dire, c’est que nous avons la possibilité d’indiquer à Firefox une série de pages Web dans lesquelles nous ne voulons pas que ce mode commence à fonctionner. Ceci est généralement utilisé dans certains sites Web un peu spéciaux dont nous savons à l’avance qu’ils sont sûrs même en utilisant HTTP . Comme nous pouvons le voir et de manière simple, grâce à ce mode implémenté par Mozilla, nous pouvons augmenter la sécurité lors de l’utilisation de notre navigateur en quelques secondes. Dans le cas où cela deviendrait plus une nuisance qu’une mesure positive, nous pouvons toujours le désactiver à nouveau si nous le souhaitons.
