User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/110.0
Steps to reproduce:
Generally just using Firefox with a few tabs open to Google Drive, Google Docs, Gmail and Google Calendar.
Actual results:
Intermittently and often, Firefox is hanging and causing my entire OS to hang as well (no mouse or keyboard input). It takes several seconds but eventually Firefox recovers and all functionality is restored.
About:Support#Graphics failure log shows a new "GFX: RenderThread detected a device reset in PostUpdate" after each hang. I can attach more debugging info including a performance profile.
Expected results:
No hanging whatsoever.

Here is a performance profile showing an over 13s wait in RefreshDriverTick which could be related. That is shows up on about:newtab is probably a red herring. I was editing a Google Doc then opened a new tab coincidentally at the time of a hang.

In case it is relevant, I am running OpenSUSE Micro OS with GNOME Wayland 43.3, Kernel 6.1.12-1-default and Firefox 110 installed via Flathub. My system is a Dell XPS 15 9520 with an Intel i7-12700H and using the Mesa Intel Graphics driver (ADL GT2). I'm happy to provide any other information that may be useful.

An update, on occasion (it has happened twice today) the entire browser just crashes without a crash report begin generated. The Firefox window disappears and the process is terminated without any crash dialogs showing. When I reopen Firefox it restores my session but there is no indication that a crash happened and neither about:crashes nor about:support show any crash reports.

I suspect this is a bug in the i915 firmware per https://gitlab.freedesktop.org/drm/intel/-/issues/6916.
Running sudo journalctl | grep -i ecode in my terminal shows several i915 0000:00:02.0: [drm] GPU HANG: ecode 12:0:00000000 messages with a timestamp close to each of the hangs noted in the Firefox performance profile.
Per the instructions at https://gitlab.freedesktop.org/drm/intel/-/issues/6916#note_1755729 I have added i915.enable_guc=2 i915.enable_psr=0 to my kernel parameters and am testing to see if this has worked around the issue.
I am closing this is INVALID since it seems to not be a Firefox bug.
