Firefox hard crashes without crash reporter

more options

On 2 of my 3 computers, Firefox crashes without a warning, at random, without a crash reporter. I have tried:

  • clean Firefox install
  • 32 bit, 64 bit
  • ESR, stable, beta, Aurora (roughly versions 60-75)
  • refresh settings
  • firefox safe mode
  • running an antivirus, disabling resident antivirus
  • windows update
  • turning off E10s
  • disabling extensions

How it manifests:

  • just crashes, no error, no warning
  • hangs, window becomes unresponsive while WERFault.exe scrapes information and sends it to MS servers

When it happens:

  • in the background
  • when I open a new tab
  • when I'm typing a URL in a tab (new or old)
  • when I switch tabs
  • when I mouse over a link
  • when I'm reading a page and not doing anything
  • even when I installed a brand new profile and literally just opened a new tab

What helped:

  • literally nothing. Turning off e10s slowed it the crash rate down and sometimes the browser runs for 10 hours, but now it's back to crashing 1-15 minutes after start

All 2 crashing + 1 stable machines have Windows 10 x64, versions 10.0.19041.153 (crashing, intel), 10.0.17134.1304 (stable, ryzen), 10.0.18362.719 (crashing, intel).

I'm not a C++ developer but I have some build tools installed and could follow a guide if you let me know how to debug it, or provide a logging build.

Please help

Somehow this website cut off the rest of my original message. Here's an abbreviated sample of one of the recent WERfault reports I have on my disk:

Hi,

Close the dialog and don't start Firefox again. Restart Firefox: Start Firefox again. Firefox will give you the option to restore the windows and tabs you had open before the crash. If Firefox crashes again after choosing to restore your windows and tabs, one of the pages you were on is causing the crash.

Thank you.
