Firefox uses hardware acceleration for page rendering (WebRender), WebGL, and video decoding. You can try switching to Firefox’s software implementation of each of those feature to see if that avoids the crashes.
To use software WebRender, set about:config pref “gfx.webrender.software” = true. To use software WebGL, set "widget.dmabuf-webgl.enabled" = false. To use software video decoding, set "media.ffmpeg.vaapi-drm-display.enabled" = false.
If those settings do avoid the crashes, please file a bug report in Bugzilla with a copy of your Firefox's about:support information. Perhaps there is a GPU driver bug that Firefox needs to work around.
- rei_ayanami 5y agoThis is exactly what I last week and this seems to have fixed the issue. But the point still stands, I don't expect my mom who uses Ubuntu to do these things.
- cpeterso 5y agoI'm glad you found a workaround. Do you know which setting change fixed the issue? If file a bug report in Bugzilla with a copy of your Firefox's about:support information, Firefox developers can work around the buggy GPU driver so other users don't experience the driver crash. https://bugzilla.mozilla.org/enter_bug.cgi https://bugzilla.mozilla.org/enter_bug.cgi
