Troubleshoot Firefox crashes (closing or quitting unexpectedly)

We understand how frustrating it is when Firefox crashes (closes or quits unexpectedly). When Firefox crashes, the Mozilla Crash Reporter will allow you to submit a crash to us so we can continue making improvements to Firefox. Here are also some things to try to get Firefox up and running optimally.

Before getting started:
  • If the page stops working because part of the page has crashed or stopped responding, try reloading the page to see if that fixes the problem.

Otherwise, follow the steps below in order.

The crash you're experiencing may have already been fixed in a new version!

Update Firefox

Every Firefox release includes a number of fixes for crashes that people have reported. Making sure you have the latest version may fix your crash. See Update Firefox to the latest release for details.

Update Windows

Make sure you have all of the latest security and stability fixes.

Update macOS

Make sure your Mac has all of the latest security and stability fixes.

Update Linux

Make sure you have all of the latest security and stability fixes.

Update your drivers

Check if your graphics drivers are up-to-date. For more information, see Upgrade your graphics drivers to use hardware acceleration and WebGL.

If your crash happens while printing, check that your printer driver is up-to-date by going to your printer manufacturer's support website. The Fix printing problems in Firefox article may also help.

Update your Internet Security software

Make sure you have the latest version of your Internet security software (including firewalls, antivirus programs, anti-spyware programs, and more).

Third-party applications (such as antivirus software, archiving software, and other tools) may load modules into Firefox. Sometimes, these applications load harmful modules that cause Firefox crashes, reduced performance, or compatibility issues. You may not notice that a malicious or unexpected module has been loaded and it may cause problems that appear to be Firefox issues. For more information, see Identify problems caused by third-party modules in Firefox for Windows.

If updating software didn't work or if Firefox crashes on startup, use the steps below to test whether the crash happens in Firefox Safe Mode or not and then follow the instructions in the recommended articles.

  1. Click the menu button Fx57menu, click , select and click Restartin the Restart Firefox in Troubleshoot Mode?dialog.

    Note: You can also start Firefox in Troubleshoot Mode by holding down the shift key while starting Firefox.holding down the option key while starting Firefox.quitting Firefox and then going to your Terminal and running:

    Fx68SafeMode

After Firefox starts in Safe Mode, test for your problem.

Note: The Refresh Firefox feature can fix many issues by restoring Firefox to its default state while saving your essential information. Consider using it before going through a lengthy troubleshooting process.

The crash still happens in Safe Mode

If your crash still happens in Safe Mode, it is not being caused by an extension, theme or hardware acceleration. Try to get help with your crash ID (see below).

The crash doesn't happen in Safe Mode

If your crash doesn't happen in Safe Mode, it is most likely because an extension, theme or hardware acceleration is causing the crash.

If updating software didn't work or if Firefox crashes on startup, use the steps below to test whether the crash happens in Firefox Troubleshoot Mode or not and then follow the instructions in the recommended articles.

  1. Click the menu button Fx57menu, click , select and click Restartin the Restart Firefox in Troubleshoot Mode?dialog.

    Note: You can also start Firefox in Troubleshoot Mode by holding down the shift key while starting Firefox.holding down the option key while starting Firefox.quitting Firefox and then going to your Terminal and running:

The crash still happens in Troubleshoot Mode

If your crash still happens in Troubleshoot Mode, it is not being caused by an extension, theme or hardware acceleration. Try to get help with your crash ID (see below).

The crash doesn't happen in Troubleshoot Mode

If your crash doesn't happen in Troubleshoot Mode, it is most likely because an extension, theme or hardware acceleration is causing the crash.

Check your RAM for errors

If Firefox crashes repeatedly, check your RAM for errors using for instance the following tool, Memtest86+Rember.

Figuring out the cause of a crash can be difficult. If you've tried the steps above and can't get Firefox to stop crashing, the instructions below will show you how to get the crash Report IDs for your most recent submitted crash reports, so our volunteers can help you.

If you can open Firefox, at least in Safe Mode:If you can open Firefox, at least in Troubleshoot Mode:

  1. In the Firefox address bar, type about:crashes and hit EnterReturn. A page listing submitted crash reports (and unsubmitted crash reports, if any) will appear.
    Fx64Beta-aboutcrashes-unsubmitted

Firefox keeps crashing at startup

A crash is what happens when Firefox closes or quits unexpectedly and the Mozilla Crash Reporter appears. If Firefox keeps crashing when you open it, this article will show you how to get it working again.

Other problems with crashing:

As a first step you should see if Firefox starts in Firefox Safe Mode. This special startup mode temporarily turns off hardware acceleration among other settings and disables installed extensions that may prevent Firefox from starting. If you can start in Firefox Safe Mode, see the article Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems for solutions.

If crashes are preventing you from starting Firefox, even in Firefox Safe Mode, a clean install will often fix the problem.

Mozilla Firefox Crashes problem fix

Firefox 84.0.1 update fixes crashes and other issues

@Resworb

I was actually a Firefox user until 2017 (before their migration to WebExtensions), because powerful extensions like Tab Mix Plus which really made my life easier made me stay with it. Mozilla killed off those extensions, and I stopped using Firefox as my primary browser. Some other incidents like Cliqz experiment, Mr Robot extension, ever new invasive telemetry and other FF experiments, lousy privacy defaults seldom improving, and other aspects didn’t help, either. After jumping ship from Firefox, I first went with Ungoogled Chromium and later with Brave.

I think none of the older Firefox versions would still be quick today if they were confronted with today’s JavaScript-heavy bloated websites. The website the browser has to load has a larger impact on the perceived performance than anything the browser itself does. Even Pale Moon, being a much newer form of “classic” Firefox than the ones you cited, chokes when you load long Reddit threads with it (although to be fair, the type of hardware you run it on also plays a vital role here). Modern Reddit is one such bloated mess that I was talking about.

I actually keep Pale Moon around for some casual browsing because believe it or not, I am also a bit nostalgic at times. I have nothing against the software itself, however the way the Pale Moon devs conduct things in the forums… If you think the occasional back and forth bickering on gHacks is bad, you haven’t seen anything yet. I dare you to go there and ask a question that has been asked before, or a question that the Pale Moon devs consider beneath them, and you will see what I mean. Others here would call me spiteful for saying things like that, so now I just point them to the forums to experience it themselves…
That being said, I am capable of differentiating between the art and the artist, so to speak, so the way they conduct things on their forums does not taint my judgment of Pale Moon as a software product. I think overall, despite their outward behavior, the developers are well-intentioned and I can’t imagine them going behind their users’ backs, e.g. by spying on them. I have much more confidence in them than in current day Mozilla, mind you.

As for Brave, since you mentioned it: It’s not for everyone, all I am saying here is that it currently fits the bill for me. It’s basically Chromium minus Google + an adblocker and some privacy-enhancing changes. If you are into customization, e.g. Vivaldi would clearly be a better choice. If you think Chrome is a good browser but don’t agree with Google spying on you, Brave serves as a drop-in replacement. Regarding the other points you’ve raised:

– I don’t know why you had extension issues, as far as I know the Brave team does not modify Chromium’s extension APIs in any way. Have you verified that it was not a bug of the extension itself? Also take note of the fact that Brave for Android doesn’t currently support extensions. In its early phase as a product, Brave used to be based on Muon, but they have given up on that, and are now based on Chromium. If you used Brave in 2016 / 2017 and found it bad, this might have changed for the better now.

– Brave disabling extensions in its Tor mode is intentional. They try to stay close to the common fingerprint of the Tor Browser Bundle, however, Brave’s Tor mode DOES NOT produce the same fingerprint as the Tor Browser Bundle. So it’s more or less only good for hiding your IP address, it’s not a real Tor replacement. Mind you that it also doesn’t have to be, because Brave is clearly not a special purpose browser. For any Tor-related tasks, I do recommend the actual Tor Browser Bundle. However, even if you were using the actual Tor Browser Bundle, people would tell you not to install extensions yourself (even though it’s technically possible, it’s not recommended), because by adding extensions yourself you’d be adding fingerprinting surface, something you presumably want to avoid by using Tor (an anonymity tool).

Crash firefox update

Firefox Keeps Crashing on Windows 10/11? How to fix it

Mozilla Firefox is one of the oldest and most trusted browsers for Windows 10 users. With millions of users, Firefox is reliable and one of the most useful browsers. But while sometimes it may work as expected, it is not uncommon for Firefox to present some problems when you try to use it. For Windows 10 users, one of the most problematic issues is when Firefox keeps crashing for no apparent reason. It can happen as soon as you turn on Firefox or when you open more than one tab on the browser.

It is important to note that this problem can occur for multiple different reasons and under different circumstances. Fortunately, there are several ways you can fix this problem once and for all and get Firefox working normally again.

Part 1: Why Does My Firefox Keep Crashing?

There are very many reasons why Firefox may be crashing on Windows 10. Some of the most common include the following;

  • The Firefox browser could be outdated and may need an update
  • It is also possible that the version of Windows 10 you are running is not up to dare
  • Mismatched cache and other conflicts of settings can cause Firefox to crash
  • When Firefox is incorrectly installed, it can also crash from time to time
  • Broken add-ons and extensions are also a major issue

Part 2: How Do I Stop Firefox from Crashing?

Just as there are varied causes of this problem, there are also a lot of different solutions that you can try. The following are some of the most effective;

Method 1: Update Firefox

Having the latest version of Firefox is one of the best ways to prevent this problem from recurring. Therefore the first thing you want to do is to check if you are running the latest version of Firefox. Follow these simple steps to do it;

Step 1: Open the Firefox browser on your computer and then click on the browser's menu. Select "Help" from the options presented and then choose "About Firefox"

Step 2: A new window will open and begin looking for available updates for Firefox. If an update is available, Firefox will download and install it immediately.

Step 3: Once the update process is complete, click on the "Restart to Update Firefox" button to complete the process.

Method 2: Clear Firefox Cache

The cache is data that Firefox and other browsers may save on your system to help websites load faster. But when the cache is corrupted it can have the opposite effect, even causing the browser itself to crash at inopportune moments. In this case, the best way to fix the problem is to clear the cache on the browser. Here's how to do it;

Step 1: Open Firefox on your computer and then click on the menu button (the three lines on the top left corner)

Step 2: Select "History" in the options presented to open a side menu with more options. In these options, click on "Clear Recent History"

Step 3: Click on the "Time Range to Clear" drop-down menu and then select "Everything"

Step 4: Select the data and items you would like to clear and then click on "Clean Now"

Restart Firefox when the process is complete to see if the problem is gone.

Method 3: Disable Firefox Add-Ons

Sometimes broken add-ons and extensions could be causing the problem and it may be a good idea to disable some of these add-ons and extensions to keep them from affecting the browser. Follow these simple steps to disable Firefox add-ons;

Step 1: Open Firefox on your computer and then click on the menu icon (three lines)

Step 2: Click on "Help"

Step 3: Select "Restart with Add-Ons Disabled" and then click "Restart" in the dialogue box that appears.

Method 4: Check for Viruses

Viruses and malware can also be a major cause of a crashing Firefox. The same is true for any software that may be incompatible with Firefox. If the problem began soon after you installed a certain program, then it is likely that the newly installed program could be incompatible with Firefox and may need to be uninstalled.

It is also important to run a full system check for your PC using powerful antivirus software. There are a lot of third-party antivirus programs you can use but you can also use Windows 10 Defender to scan your system.

Method 5: Update your Drivers

Sometimes the problem is not with Firefox but with the drivers on your computer. Therefore, updating the drivers could help keep Firefox from crashing. To update drivers on your Windows 10 system, follow these simple steps;

Step 1: Press the Windows Key + R on your keyboard to open the Run dialogue

Step 2: Type in "devmgmt.msc" into the dialogue box and then press "Enter". This will open the Device Manager.

Step 3: You should see a list of all the devices on your device. Any devices that need a critical update will be marked with a yellow exclamation mark.

Step 4: if you don't see any critical updates, locate the most important drivers, necessary to keep your computer running normally. Right-click on the device and then select "Update Driver"

Step 5: Follow the on-screen instructions and when the update is complete, restart the computer to finish the process. Moreover, you can also learn how to fix the Chrome keeps crashing issue.


Part 3: How Do I View a Firefox Crash Report?

After implementing some or all of the solutions above, you may want to check the crash reports to determine if the problem has gone away. Thankfully checking crash reports on Firefox is very easy; just open Firefox and then type in "about crashes" in the address bar. Press "Enter" and the crash report will appear.

Click on "View" next to the crash report you would like to open to see the crash report.

People Also Ask

  • What to do if Firefox keeps crashing

    The first solution is to update your software as it just might be outdated. You can also update Windows OS and your drivers. Try to run your system in Safe Mode to see if Firefox will keep crashing. If it still crashing, then your extension or hardware acceleration is not the cause, hence no need to fix them.

  • Why does my tab keep crashing?

    If malware is installed on your PC, it could cause your tab to keep crashing. The issue may also arise from the Firefox hardware acceleration or an outdated graphics display driver.

  • Why won't Firefox open on my computer?

    Firefox may not open on your computer because of a corrupt add-on. If your Firefox opens in Safe Mode, then this could be the case. If it does not open even in Safe Mode, then the problem could be from the software itself or your user preference files.

Instead of fixing issues with Firefox, upgrade to a better browser: Opera
You deserve a better browser ! 350 million people use Opera daily, a fully-fledged navigation experience that comes with various built-in packages, enhanced resource consumption and great design.Here's what Opera can do:
  • Easy migration: use the Opera assistant to transfer exiting Firefox data, in just a few steps
  • Optimize resource usage: your RAM memory is used more efficiently than Firefox does
  • Enhanced privacy: free and unlimited VPN integrated
  • No ads: built-in Ad Blocker speeds up loading of pages and protects against data-mining
  • Download Opera

Firefox is one of the best browsers for Windows. However, that doesn’t mean the software runs perfectly.

Firefox occasionally crashes and closes unexpectedly. When the software crashes, a Mozilla Crash Reporter window opens stating, Firefox had a problem and crashed. Then you’ll need to press the Restart Firefox button on that window to reopen the browser.

Various things can trigger a Firefox crash. A Firefox crash can be due to an outdated plug-in, faulty add-on, malware, hardware acceleration, outdated software, and more besides. These are a few potential fixes for a Firefox browser that’s crashing with regularity.


How to fix Firefox had a problem and crashed error

1. Consider an alternative

These days, users have plenty of choices when it comes to web-browsers. You don’t really need to stick with one if it gives you headaches.

Switching browsers is very easy because all major ones have the ability to import and export bookmarks and settings.

What do you like about Firefox? Dark-mode? Perhaps ad-blocker? Extensions? Video pop-up?

Whatever it is, the Opera browser has them all. Plus, you get some extra goodies as well such as:

  • Free and unlimited proxy VPN
  • Group tabs together in different Workspaces
  • Integrated Facebook Messenger and WhatsApp straight in the sidebar

What’s not to love? So, if Firefox keeps crashing, now might be a good time to give Opera a chance.

2. Clear Firefox’s Cache, Cookies, and Page History

You should also clear Firefox‘s cache, cookie and page history every month. The accumulation of cache, cookie, and page history files piling up will at least slow down the browser; and can also cause it to hang or freeze. For example, the page history can interfere with Firefox‘s startup.

As such, Firefox will run more smoothly if you clear its cache, cookies and page history with some regularity. This is how you can do that with the freeware CCleaner.

  1. Open CCleaner and then click CustomClean on the left of its window.
  2. Click Applications and then select Firefox‘s Internet Cache, Internet History, and Cookies checkboxes.
  3. Press the Analyze button to run a preliminary scan that will show you how many files CCleaner will erase.
  4. Click the Run Cleaner button and press OK to clear the cache, page history, and cookies.

Why use CCleaner? Because it can also be used for various other programs as well. With one simple scan, it can clean up your PC of old files and perform some registry cleanup.

This means your computer will be running faster and with fewer chances of encountering errors.

3. Scan for Malware

Malware crashes most types of software. Firefox will probably crash more often if there’s malware on the desktop or laptop.

As such, scanning for and purging malware with anti-virus software can also fix Firefox browsers that are crashing. It’s better to do that with multiple utilities that detect different types of malware.

Malwarebytes is your top choice. It performs much better than regular antivirus solutions that you might have heard of.

Perform a full scan with Malwarebytes

It works very simple. First, you scan your computer. Then you delete or quarantine any files that were found.

Run a System Scan to discover potential errors

Run a PC Scan with Restoro Repair Tool to find errors causing security problems and slowdowns. After the scan is complete, the repair process will replace damaged files with fresh Windows files and components.

Sometimes a reboot of your computer might be necessary. Once your system is clean, go back to Firefox. It should stop crashing.

4. Update Firefox

  1. Press the Open menu button at the top right of the browser.
  2. Click the Open Help Menu (question mark) button, and select About Firefox to open the window below.Restart to update Firefox
  3. The About Mozilla Firefox window checks for and downloads updates. Press the Restart Firefox to Update button when the updates are ready.

Mozilla usually irons out a few bugs in every Firefox version. As such, make sure you’re running the latest Firefox release.


5. Check for Windows Updates

You should also update Windows to ensure that software runs more smoothly. Windows updates provide security updates and can also fix software bugs. This is how you can check for updates in Windows 10.

  1. Press the Cortanabutton on the taskbar, and then you can enter Windows Update in the search box.
  2. Select Check for Updates to open the window shown directly below.
  3. Press the Check for updates button.
  4. Windows will tell you if updates are available. Windows will then automatically download and install available updates.

6. Update the Flash Plug-in

  1. First, open this page to check if Firefox‘s Flash plug-in is outdated. The page will tell you if you need to update the plug-in.
  2. You can update the Flash plug-in at this website page. First, deselect the optional offer checkboxes on that page if you don’t need the extra software.
  3. Press Install now to save the latest Flash installer to Windows.
  4. Close Firefox and open the folder that includes the Flash installer. Then you can open the installer to update Flash.

Flash is the only plug-in Firefox really supports these days. Browser developers have abandoned plug-ins precisely because of their vulnerabilities, and an antiquated Flash plug-in can also freeze or crash Firefox in some way. As such, updating Flash, if it needs updating, will also ensure Firefox runs more smoothly.


7. Run Firefox in Safe Mode

  1. Press the Open menu button at the top right of Firefox‘s window.
  2. Click the Open Help Menu question mark button, and select the Restart with Add-ons Disabled option from the menu.
  3. A Restart with Add-ons Disabled window will then open. Press the Restart button to confirm.
  4. A Firefox Safe Mode dialog window opens, which includes a Start in Safe Mode button. Press that button to launch the browser in Safe Mode.

Firefox includes a Safe Mode that you can troubleshoot the browser with. That’s a troubleshooting tool that switches add-ons and hardware acceleration off and restores the browser’s default theme.

If Firefox doesn’t crash in Safe Mode, it must be an add-on, theme, or hardware acceleration crashing the browser.


8. Switch off Firefox Add-ons

To switch Firefox’s add-ons off, click Open menu > Add-ons to open the tab below.

Manage Addons in Firefox

  1. Toggle the Add-ons’ button to disable it.
  2. Then toggle again to reactivate the extensions. Restart Firefox after switching each add-on back on.
  3. When you discover the faulty add-on that’s crashing the browser, press its three-dotted button, and click on the Remove button on the Add-ons Manager tab.

If Firefox doesn’t crash in Safe Mode, then an add-on is probably crashing the browser. You could just continue browsing in Safe Mode with all the add-ons off. However, you can also switch the add-ons off manually.

Switch all the extensions off, and then enable each of them again one at a time to discover the add-on that’s crashing the browser.


9. Switch off Hardware Acceleration

Firefox’s hardware acceleration makes the most of your desktop’s or laptop’s graphics card to render objects on web pages.

However, hardware acceleration doesn’t always work so well with some graphics cards and drivers and can also crash Firefox. So switching hardware acceleration off can be an effective fix for Firefox crashes.

  1. Click the Open menu button and select Preferences to open the tab below.Disable Hardware acceleration in Firefox
  2. Scroll down until you find the Performance section.
  3. Untick the Use recommended performance settings.
  4. A new option will show called Use hardware acceleration when available. Deselect that setting to switch hardware acceleration off.
  5. Then restart the Firefox browser.

10. Update the Graphics Card Driver

  1. Press the Win key + X hotkey to open the Win X menu.
  2. Select Device Manager from that menu.
  3. Click Display adapters in Device Manager, and then you can right-click the graphics card listed there to open the context menu.
  4. Select the Update Driver Software option to open the window shown directly below.
  5. Select the Search automatically for updated driver software option to scan for driver updates.
  6. Windows will automatically install available graphics card driver updates.
  7. Restart the OS if Windows does install a driver update.

Updating an outmoded graphics card driver can also fix Firefox hardware acceleration crashes. You can update drivers with third-party software, Windows tools or by downloading them from manufacturer websites yourself.

11. Reset the Browser

  1. Press the Open menu and Open Help Menu buttons in Firefox.
  2. Then you can select Troubleshooting Information to open the page tab directly below.Firefox troubleshooting page for reset or safe mode
  3. Press the Refresh Firefox button.
  4. Click Refresh Firefox in the window that opens to confirm the selected option.
  5. Firefox then closes and reverts to its default configuration. Thereafter, a window opens that includes a Finish button, which you can press to reopen the browser.

Resetting Firefox is another good way to fix crashes. Refreshing the browser restores it to its default settings and removes extensions and themes that can crash Firefox. However, you will retain your bookmarks and cookies after resetting the browser.


Those fixes will ensure Firefox crashes less often at least. If you fill out the Mozilla Crash Reporter, you can also get some feedback for fixing the crash from Mozilla staff.
