I am running FF 34 on Windows 8.1 64-bit, AMD driver 14.12 (current as of today), current anti-virus (Nod32), and all plug-ins are updated. I have EMET running as well.

After looking at the 5 most recent crashes, they all have a cause of EXCEPTION_ACCESS_VIOLATION_READ with a memory address of 0x5a5a5a62. Here are the crash IDs:

bp-e5d1468e-4b47-43b5-8d03-50d5e2141229 bp-96961de6-a249-4cda-b228-95ca22141229 bp-ec8ff70e-d6b5-4b67-b852-fd4d32141228 bp-a3a2644d-c7fa-4c89-bf82-0a5012141228 bp-46003f2a-2006-48ea-b030-f59ba2141228

Is anyone able to help? Thanks in advance :)

Alright does this happen all the time or at random times, and if it happens all the time please try to open Firefox in safe mode and tell me if it still crashes. https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-sa...

It has been crashing in safe mode, but I put it back in just in case. It crashes randomly, not related to any particular web page, and I can be filling in a form / reading a long article / watching a video / doing any number of things (or not interacting with it at all with it minimised) when it crashes.

Have you tried resetting Firefox? This solves a lot of problems and if you have already let me know but I think this may solve your problem and once you reset it don't install anything and see if it still crashes. If it doesn't install your plugins one by one and each install test to see if it crashes. This can help you reset Firefox and let me know if it works. How to reset Firefox

In case it helps, here's a crash from safe mode that just happened:

bp-ee9d2872-bc9b-457f-8133-d6f3e2141229

It's too late to do a reset atm, but I will give that a shot after work tomorrow.

You can also check for issues caused by plugins and set all plugins to "Ask to Activate" on the "Firefox/Tools > Add-ons > Plugins" page (plugins are not affected by Firefox Safe Mode)

Reset FF and tried disabling / setting to "ask to activate" for all plugins; still crashing, but with a slightly different error code: EXCEPTION_ACCESS_VIOLATION_EXEC at address 0x9f7f1c0

The latest crash, post reset, is:

bp-4166f37d-ad52-4094-8b50-ba0822141229

Thanks for the suggestions :)

Thanks for the reminder to run sfc. There was some corruption in the system files - I used the following two commands, both in safe mode and in regular mode, and eventually got them both to run cleanly (there were hanging issues). I rebooted after both commands said all the corruption had been fixed.

dism /online /cleanup-image /restorehealth sfc /scannow

The dism command is apparently the proper one to use for Win8, although sfc does still work.

My graphics drivers are current - I had mentioned that in the first post :)

Here is the latest crash - post fix and reboot:

Thanks again for all your input.

Remember one thing about computer programs . . . . . . After you check for an upgrade, then the upgrade is posted.


When you crashed, what were you doing and where? How long?

winmm.dll = Windows Multimedia

mswsock.dll = Microsoft

combase.dll = Microsoft

KERNELBASE.dll = Microsoft

Do a malware check with several malware scanning programs on the Windows computer. Please scan with all programs because each program detects different malware. All these programs have free versions.

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

You can also do a check for a rootkit infection with TDSSKiller.

Ran all of the recommended antivirus cleaners, uninstalling and rebooting in between each one. All they found were advertising tracking cookies (which is great, but doesn't solve my problem *grin*). The crashing has slowed down significantly (no longer every 1-2 hours), but it is still happening.

The crashes happen when I am reading a page without interacting, filling a form in, loading a page, or have the browser minimised in the background - it doesn't seem to matter what I'm doing.

Latest crash:

  • My video drivers are up to date (I just re-checked)
  • None of the suggested AV programs can find any malware on my system
  • Neither sfc nor dism can find any corruption in my system files
  • I have hardware acceleration turned off in the FF options

Any other suggestions? Thanks in advance.
