Unhandled exception at 0x00007FF836A36FB1 (xul.dll) in firefox.exe: 0xC0000005: Access violation reading location 0x0000029F7A02DFDC.

Hi Mozilla,

I am experiencing repeated crashes when opening Firefox (both standard and developer versions). The crash happens within 30 seconds of opening Firefox. The behavior just before the crash involves a slight hang, and then a crash.

I am able to debug with Visual Studio, and can see the following error message: Unhandled exception at 0x00007FF836A36FB1 (xul.dll) in firefox.exe: 0xC0000005: Access violation reading location 0x0000029F7A02DFDC.

I have tried many, many avenues, including: - Freshly reinstalling Windows 10 Enterprise - Running Firefox as Admin - Starting Firefox in Safe Mode - Refreshing Firefox - Reinstalling Firefox - Disabling/Enabling hw acceleration - Running a malware scan - Installing all necessary Windows updates

If I have some time, I will likely get the latest source and run it locally in debug. However, I am a C# dev, and not a C++ dev, so it may not be all that helpful.

Firefox Details: v62.0

PC Details: i7-7700K GTX 1080 16GB DDR4 @ 3200 Samsung Evo 960 EVO

The Firefox AppData folder is empty, and I am unable to find a proper crash report for you, but I do have a disassembly from Visual Studio. It seems to be crashing in _sk_gather_bgra_hsw().

Any help would be greatly appreciated!

Please let me know if you need any further info.

Cheers, Keagan

Soluzione scelta

I have found the issue!

I can safely say that the issue is caused by a failing CPU! I inserted another CPU (i5-7600K) and booted up. Firefox worked flawlessly!

Thanks for your help guys. This is officially the only thread on the internet that links this error with a potential CPU failure. May help somebody, somewhere.

Cheers, K

Sorry to hear having issues make sure to include the bp-

The crash report is several pages of data. We need the report numbers to see the whole report.

  1. Enter about:crashes in the Firefox address bar and press Enter. A Submitted Crash Reports list will appear, similar to the one shown below.
  2. Copy the 5 most recent Report IDs that start with bp- and then go back to your forum question and paste those IDs into the "Post a Reply" box.

Note: If a recent Report ID does not start with bp- click on it to submit the report.

(Please don't take a screenshot of your crashes, just copy and paste the IDs. The below image is just an example of what your Firefox screen should look like.)

Since you have no crash report try crashing it to get one.

You have tried all those things already. Something is causing Firefox to crash. With out the report it is beyond me in VB.

Please try : 1) Use the Windows key + X keyboard shortcut to open the Power User menu and select Command Prompt (Admin). 2) Type or Copy/Paste the following command and press Enter: 3) DISM /Online /Cleanup-Image /RestoreHealth 4) Reboot

Then try : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files , C:\Program Files(x86) & C:\ProgramData Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved.

I have followed the steps outlined above. It seems all English x64 builds are corrupt. This led me to install an x86 version... I occasionally get tab crashes now, but these are caught and dealt with appropriately (without killing the firefox process).

This can be seen in the following crash report: bp-0821454e-bfea-4747-bbd7-dba430180907

Signature js::DecompressStringChunk

Hi, so the problem is still with js which is beyond me.

Could it be your connection/network driver or Firewall A/V that is the issue ?

Issues come up with : Avast/AVG, Kaspersky, BitDefender, ESET & sometimes McAfee

I have found the issue!

I can safely say that the issue is caused by a failing CPU! I inserted another CPU (i5-7600K) and booted up. Firefox worked flawlessly!

Thanks for your help guys. This is officially the only thread on the internet that links this error with a potential CPU failure. May help somebody, somewhere.

Cheers, K
