Tab consistently crashes while loading 3D scene - WebGL problem?

The Tab crashes while loading a particular 3D web scene:

The crash has happened consistently on my machine as well as others. The scene loads and works fine in Chrome (mobile & desktop), MS Edge, Samsung Mobile Browser. One iPhone user did report a crash but I do not know which browser nor version they were using. SafeMode just gives the expected 'WebGL is not installed on your browser.'

Digging through the crash reports (listed below) I see a lot of references to WebGL. But these reports go way beyond my tech skills.

I'll gladly fix any problem in my 3D scenes that is offending Firefox (my preferred browser) but I just don't know what the problem is.

Thanks for any help & advice!

Try to disable WebRender.

You can check the about:support page (Graphics) to see whether WebRender is enabled. Try to set this pref to false on the about:config page.

  • gfx.webrender.picture-caching = false

Close and restart Firefox after modifying this pref for the change to take effect If this didn't help then modify this pref as well and restart Firefox.

  • gfx.webrender.force-disabled = true

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

You can create a new profile to test if your current profile is causing the problem.

See "Creating a profile":

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
