As it says the error is in firefox.exe, I assumed it was firefox. Am I wrong, it not firefox, firefox.exe is part of something else?

Explain in detail. What is the exact wording of the error code ?

There is more to it than that. Is it Blue Screen of Death your getting ?

Is everything still running besides Firefox ?

Firefox does not have that error code and it is too long for Microsoft.

Just this.

See if there is any crash reports from today, just need 3 in the bp- file as directed here : https://support.mozilla.org/en-US/kb/firefox-crashes-asking-support

There are no related error codes for this problem. There are 2 errror reports but not related to this, weird or what.

Did you run DISM  ? Then Reboot fixed anything ?

uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files and C:\Program Files(x86) 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. But you should make a back up before you do : https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

Reinstall with Current Release Firefox 57.0.2 with a Full Version Installer https://www.mozilla.org/firefox/all/

Please let us know if this solved your issue or if need further assistance.

I'm not going to claim victory yet but it looks promising. No more error. A few days error free then yay.

Ok just to make sure here are two things.

1st just check that it is unticked : go to the Firefox 3 Bar Menu --> Options --> Privacy & Security panel and under Permissions check the setting to Prevent Accessibility Services from accessing your browser.

The below one monitor your Task Manager and if it gets extreme and lagging then do below :

Go the 3 Bar Menu then Options --> General --> Performance and untick everything. change the recommended size lower then see how it runs. Note: 1 = No Multiprocessor = slow again. Try 2 Restart Firefox after making these changes please.
