More information and further troubleshooting steps can be found in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

There were 10+ crashes that happened on 12May17 that don't appear here, so I didn't think these crash reports were relevant.

Safe mode still crashes, but Firefox will just close completely and no error windows will pop up.

Just started getting this error message (screenshot attached)

Attached is a screenshot of the typical crash. There is no error code

The crash reports show different problems.

Perform a System File Check to fix corrupted system files

Let’s do a full clean re-install; Download Firefox For All languages And Systems {web link}

Save the file. Then Close Firefox.

Using your file browser, open the Programs Folder on your computer.

Windows: C:\Program Files C:\Program Files (x86)

Mac: Open the "Applications" folder. https://support.mozilla.org/en-US/kb/how-download-and-install-firefox-mac

Linux: Check your user manual. If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it. See Install Firefox on Linux; https://support.mozilla.org/en-US/kb/install-firefox-linux

If you downloaded and installed the binary package from the Firefox download page, simply remove the folder Firefox in your home directory. http://www.mozilla.org/firefox#desktop ++++++++++++++++++++++++++++ Do Not remove the profiles folder.

Look for, and rename any Mozilla or Firefox program folders by adding .old to them. Do not rename the Mozilla Thunderbird folder if there is one.

After rebooting the computer, run a registry scanner if you have one. Then run the installer. If all goes well, remove the OLD folders when you are done. +++++++++++++++++++++++++++ If there is a problem, start your Computer in safe mode and try again.

I did the file system check. After the scan is said that "Windows Resource Protection did not find any integrity violations."

I've tried firefox in safe mode, refreshed firefox, completely uninstalled firefox then deleted all of the program folders. Firefox still crashes.

No other programs are affected and this only happened after the most recent firefox update.

Here is one that happened today: bp-c1a9da4b-d598-4c71-beac-b957b1170515

What are you using to protect your computer? As a test, disable it.

You mean like a firewall or antivirus? I ran windows defender and it didn't find anything. I don't know if there's a way to deactivate it though? It's on a work network so I can't control the firewalls.

Chrome and internet explorer work fine though.

Have your IT check the computer. This could be related to the work system.

IT won't work on personal computers. Firefox will work on other computers on the network.

This is a brand new computer I'm not sure why firefox is crashing. I've made sure everything is updated

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen or hold down the Shift key) to see if that has effect.

Do a malware check with several malware scanning programs on the Windows computer.

• https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware

Please scan with all programs because each program detects different malware. All these programs have free versions.

Make sure you update each program to get the latest version of their databases before doing a scan.

As mentioned in my posts above, I have already scanned with windows defender and found nothing AND tried booting in safe mode.

You should scan with all the tools mentioned.

Firefox constantly crashes after the latest update. Here's everything I've tried that hasn't fixed the problem: -safe mode -clean uninstall/install (including deleting the Firefox program folder) -run windows defender (nothing found) -windows system file check (nothing found) -used google chrome and internet explorer (both work fine without issues)

I will let others try to interpret the crash IDs and to suggest a way forward. One crash may relate to use of Norton's software and one seems to be a hang or crash related to FlashPlayer use.

Unless others comeupo with better and trargetted solutions I suggest that after you have scanned with all the other tools, if that does not help in resolving the matter that you next try Firefox in its safe mode and with FlashPLayer disabled and post another coupler of Crash IDs from crashes in safe mode.

Please say what the Norton Sofware is that you use, giving the full name and version number. Is that Norton software fully up to date ?

I had aken109 run System File Checker, and do a clean reinstall. https://support.mozilla.org/en-US/questions/1159904#answer-968473

Also try to update to the Firefox 53.0.3 release (Help > About).

I notice that the crash with Flash is about Flash 23.0.0.207

• https://crash-stats.mozilla.com/report/index/f61b4409-d06d-4c07-a4c9-580930170515

Did you recently update Flash or are you using a different computer?
