We’re happily browsing the internet or doing research or whatever, and suddenly your browser freezes up and stops your day dead in its tracks. If you are using Mozilla Firefox, here is how to troubleshoot Mozilla Firefox browser if it crashes, hangs, or stops functioning.

Browsers

Browsing the internet has become an integral part of our daily life, whether we are at home or at the office working or checking news and happenings on the go. We access the internet through browsers that lets us access, download and process information from the world wide web aka the internet. Some examples of browsers are Google Chrome, Opera, Opera mini, Internet Explorer and Mozilla Firefox.

To Troubleshoot Mozilla Firefox

If you are using Mozilla Firefox and it crashes on you then here are some of the measures you can take to troubleshoot Mozilla Firefox to get up and running again:

  • Activate Safe Mode
    • The safe mode loads this browser without the add-ons when you hold the shift key when starting Firefox. The other was is to click the browser menu, point to help, and choose restart Firefox with add-ons disabled. If you continue using the safe mode and the browser does not crash, this implies that there is an issue with one of your add-ons.
    • You may want to leave safe mode and restart the browser with the add-ons loaded. To troubleshoot Mozilla Firefox after it crashes again you can then disable add-ons one after the other to identify the problematic one.
  • Reset Firefox
    • There can be issues with your profile folder that Firefox used to store your personal data. All bookmarks, browser history, cookie and auto-fill information and saved passwords will be transferred to a new profile folder. Remember that you will lose themes and extensions (causes of most browser crashes) and any other site-specific information after a reset on the browser.
    • Open the Firefox menu, point to Help and select troubleshooting information and then click the reset Firefox button. If Firefox crashes after you install your extensions, then most probably one of your extensions is causing the issue. You need to reinstall these one by one to identify the one that is causing the need to troubleshoot Mozilla Firefox crash.
  • Disable Hardware Acceleration
    • Web pages run faster and web pages load faster with the hardware acceleration feature of Firefox. Sometimes this feature can cause issues with some graphic cards and drivers. To troubleshoot a Mozilla Firefox crash, check if this feature is an issue for your browser by selecting options after clicking the Firefox button and then click Advanced options, then untick ‘use hardware acceleration when available.’
  • Check for Malware
    • Firefox can crash due to presence of malware on your system so you need to scan your system regularly with a good antivirus program. If you already use one and still have the issue, check with using an alternate antivirus program just to get a second opinion.
  • Update the Software
    • Check for updates frequently for all the software you use on your personal computer so that you have the latest updates, such as virus definitions for example that are not up to date can cause the browser to crash.

    A Few Words about Mozilla Firefox Crashes

    The situation where a program or applications closes unexpectedly and fails to respond to your attempts to start it is called a crash. If your Firefox happen to crash, you should see the Crash Reporter dialog prompting you to report the experienced issue to the developers. You use this handy option and make your problem known to professionals that may prevent similar problems from happening in the future. And now let’s take a closer look at possible solutions to the problem in question.

    Solution 1

    If the Firefox browser crashes at startup, check whether the same happens in Safe Mode.

    If the issue still persists in Safe Mode, we suggest that you use the Refresh Firefox feature that comes in handy when it’s necessary to restore the program to its default state without losing your essential information.

    1. Go the Firefox menu and select the “Help” option from there.
    2. Choose “Restart with Add-ons Disabled…” Alternatively, you may take advantage of the handy shortcut to quickly launch Firefox in Safe Mode. All you need to do is to press and hold the Shift button while firing up Firefox.
    3. Once you see the Safe Mode dialog, select the “Start in Safe Mode” option.

    After that you may start troubleshooting the crash.

    If you notice that Firefox works normally in Safe Mode, the odds are good your extension or hardware acceleration is responsible for its crashing in Normal Mode. We recommend that you refer to the Firefox guide that will help you troubleshoot extensions, themes, and hardware acceleration issues and get your favourite browser up and running again.

    Solution 2

    Another solution you can try out if your Firefox crashes at startup is a clean reinstall.

    First, you need to perform a proper uninstallation of the current version of Firefox on your PC. To do it, it’s necessary to close the browser and select the “Control Panel” option from your Windows menu.

    Once the panel is open, click on the Uninstall a program link under “Programs.”

    Find Mozilla Firefox on the drop-down list of the programs currently installed on your computer. Select it and press the “Uninstall” button. In the Uninstall Wizard window click on “Next” and then select “Uninstall” option again. Finally, you’ll need to click “Finish” to complete the uninstallation process.

    Once you uninstall Firefox, remove its installation folder in:

    • C:\Program Files\Mozilla Firefox
    • C:\Program Files (x86)\Mozilla Firefox

    Get a new copy of Firefox from either the Mozilla Firefox official website or RocketFiles.com. Double-click the new file and follow the onscreen instruction to get through the installation of the fresh copy.

    Solution 3

    A certain program may crash as a result of the installation of some incompatible software. The same goes for Firefox. So, you need to check your system for suspicious software that may be responsible for your browser crash. It’s also a good idea to run an antivirus program across your system to make sure your PC is free from viruses and any other malware.

    Solution 4

    The surest way to quickly and effectively troubleshoot a Firefox crack is to make certain you have the latest version of the program installed on your Windows PC. Though Firefox is designed to update automatically as soon as the new version is released, you can always resort to a manual update.

    1. Head to your browser menu. Click “Help” and then choose “About Firefox” option.
    2. As soon as the new window appears, the program will start looking available updates. If there is one, Firefox will download it onto your PC.
    3. Once the new download is saved to your Downloads folder, make sure to restart the system by hitting the “Restart to update Firefox” button.

    Now that you have a fresh install of a new Firefox version, the troubleshooting process will not take long.

    Solution 5

    If the crash still happens in Safe mode, then it is not being caused by extension themes or hardware accelerations. You must then get help with your crash ID

    Sometimes figuring out the exact problem might be challenging and may require expert help from the experts over at Mozilla. Hopefully, though, the above fixes will help you get some relief from the crashing browser.

    Tip / Trick

    How to troubleshoot mozilla firefox crashesYou are browsing something serious and urgent and your Mozilla Firefox keeps crashing. Are you fed up and unsure about how to solve this problem? Then, following the tips and tricks discussed below will help you to troubleshoot the issues and fix them.

    When Mozilla Firefox keeps crashing, it could be for multiple reasons. Most of the time, you can fix Firefox crashes by re-setting Firefox or by going to Safe Mode. But in some cases, these tricks won’t work. You have to keep in mind that a web browser is a complicated piece of application that depends on the number of software, plug-ins, drivers, and security programs installed on your computer. So, troubleshooting the correct reason for the crash is a complicated process.

    Tips and Tricks for Troubleshooting When Mozilla Firefox Keeps Crashing

    1. Changing to Safe Mode: Mozilla Firefox has a safe mode option that can be enabled. In the safe mode, it loads the browser without loading the add-ons. To enable the safe mode, go to the Firefox menu, click Help, and select the “Restart with Add-ons disabled” option. If the safe mode is working without any issues, then it means one of the add-ons is having issues and that is causing Firefox to crash. You can identify those add-ons by enabling them one by one and checking if Firefox is crashes after you enable a particular add-on. Once you identify the add-on that causes the crash, remove it permanently and then continue to work with Firefox without any crashes.
    2. Resetting Firefox: Mozilla Firefox uses a profile folder to store personal data. So when your Mozilla Firefox keeps crashing, rather than trying to fix the issues inside the profile folder, do a quick reset. When you reset Firefox, it will create a new profile folder and move all the history, bookmarks, passwords and cookies to that folder. The extensions and themes are not moved to this newly created profile folder. In most cases, crashes are caused by these extensions and themes. So, resetting Firefox is the best option for troubleshooting when Mozilla Firefox keeps crashing.
    3. Check for Malware: Malware can cause crashes and damage your web browser, as well as your system. Therefore, checking for malware using good anti-virus software is another option when Mozilla Firefox keeps crashing.
    4. Disabling hardware extensions: Mozilla Firefox hardware acceleration uses your computer’s graphic card to display objects and texts from web pages. But in some cases, the extensions can cause damage to your system’s graphic cards. Therefore, by disabling the hardware extensions, you can check if Firefox crashes afterward. To disable the extensions, go to Options > Advanced icon. Now uncheck the option “Use hardware acceleration when available” checkbox.
    • Update software for avoiding crashes: Updating software is a good option to avoid crashes. When your Mozilla Firefox keeps crashing, one of the reasons could be outdated software. So, be sure to update the software for Firefox, Plug-ins, Extensions and Themes, Graphic Drivers, Anti-Virus Software and the Windows OS.

    Conclusion

    Mozilla Firefox is one of the best web browsers that is available now. When your Mozilla Firefox keeps crashing, try one of the tips and tricks given above to fix the issue.

If only one update is found, an “Update now” button will appear next to the extension. If more than one updates are found, a dialog box will appear, allowing you to install all of the updates at once.
    • If you are using an older version of Firefox , open up the “Tools” menu and choose “Options”. In the Options window, switch to the “Advanced” panel and locate the “Check N ow” button underneath the heading “Software Update”. Make sure that the “My Extensions and Themes” checkbox is ticked.

    Note that not all extension updates will be available through the update system. You may have to find updates for these extensions manually (i.e. by visiting their homepage and installing the latest version over the top of the current version).

    You may also find extensions at the following sites:

    • https://addons.mozilla.org
    • http://www.extensionsmirror.nl
    • http://extensionroom.mozdev.org

    Note that installing extensions from sites other than Mozilla Update is done entirely at your own risk.

    4. Update Plugins

    Plugins are programs that work within Firefox and allow you to experience multimedia content such as video, animation or sound. As with Firefox and Firefox extensions, the latest versions are always the best. It is therefore extremely important that you have the latest version of each plugin that you use.

    Plugins that are known to cause crashing in Firefox if they are not updated include:

    • Macromedia Flash (http://www.macromedia.com/go/getflashplayer)
    • Real Player (http://www.real.com)
    • Real Alternative (http://www.codecguide.com/about_real.htm)
    • Java (http://www.java.com/en/download/)

    There may, of course, be problematic plugins that are not included in this list. You can check which you have installed by typing “about:plugins” in the location bar and pressing Enter.

    Firefox may crash when:

    • You are using the VLC Media Player plugin and view VMW media – this can be caused by having the VLC Media Player installed, which includes its own browser plugin. This plugin conflicts with the WMP plugin, so you need to remove the VLC plugin for embedded WMV files to play properly.
    • Windows Firewall is disabled – If you are using Windows XP SP2, a known Windows fault may cause Firefox and other web browsers to crash after a few minutes if you have disabled the in-built Windows Firewall. Microsoft has a support page detailing this problem, which is expected to be resolved in Windows XP SP3. If enabling the Windows Firewall fixes your problem but you do not wish to use it, you can install the hotfix detailed in the article. Unfortunately, to obtain the hotfix you must contact Microsoft directly.
    • Downloading files – Close Firefox, then search for and delete “downloads.rdf” from your hard disk drive (you will need to search for hidden and system files). You may also be able to solve this problem by clearing the Download History from the Clear Private Data tool, located on the Tools menu.

    6. Still experiencing problems?

    If all of the above have been ruled out as causes of your crashing problems, there’s still a good chance that the problem can be solved or located:

    • Try the standard diagnostic.
    • Start a new topic in the Firefox Support forum and, assuming that you have the Quality Feedback Agent (crash data tool) installed, include your crash ID numbers (which can help support forum members and developers find and fix the cause of the crash). To find your crash ID numbers, search your computer for “talkback.exe” (it should be located within your Firefox install directory) and run it. Select your recent crashes and click Edit > “Copy Currently Selected Incident(s)”.

    7. Shouldn’t someone fix these crashes?

    If you can successfully help us to locate the cause of a crash, search Bugzilla to see if a bug has been filed, comment on that bug with your crash ID data if appropriate. If you are unsure or need help filing a new bug, ask support forum regulars or post in the “Firefox Bugs” forum for assistance.

    Be advised that bugs should only be filed if the problem exists with the most recent release of Firefox. If upgrading to the latest version of Firefox solves your problem, you do not need to file a bug.

    8. I have a solution or crash cause that should be added to this FAQ

    Please feel free to send me a private message with your additions to this thread. Please don’t contact me via private messaging with individual problems, you’re more likely to get a response if you post in the public forums.

    9. How can I help others?

    If you’re a support forum regular and you want to help people that are experiencing crashes, get hold of some Talkback ID numbers and plug them in to the Talkback FastFind tool. It will help you track down related bugs and locate where the crash occurred.

    To Troubleshoot Mozilla Firefox Crashes follow the steps :

    How to troubleshoot mozilla firefox crashes

    Step 1-Use Safe Mode -Firefox has a Safe Mode that loads Firefox without loading your add-ons. To activate Safe Mode-> click the Firefox menu->point to Help, and select Restart with Add-ons Disabled. You can also enter Safe Mode by holding the Shift key while starting Firefox.

    Try using Safe Mode for a while if Firefox is crashing. If Safe Mode works properly, the problem is with one of your add-ons. You may want to leave Safe Mode and disable add-ons one-by-one until you identify the add-on causing the problem.
