Created attachment 757009 [details] emerge --info Everyday I use meet.google.com and after I installed Mozilla Firefox 91.3.0esr it start freezing often. The most reproducible may be meet with opening youtube tab while meeting goes. Tested with i3wm X11, Sway on Wayland, qtile X11 (everyday usage), qtile on Wayland. I rebuilt FF with and without wayland USE flag - the same behaviour.
Using binary 94.0.2 (64-bit) version seems fine. I need some time to rebuild 91.3.0esr again to grab its about:support information.
I can confirm this. Today big update with firefox reemerge (because of media-libs/harfbuzz-2.9.1? I thought I remembered from emerge -a output) and firefox freezes. -bin on another machine (less updated) works.
Thank you for the report. We need to have all information at hand before ticket assignment. Please provide * the complete build.log as attachment as described on https://wiki.gentoo.org/wiki/Attach_the_logs_to_the_bug_ticket
Most likely related to https://bugs.gentoo.org/822138 - the fix is queued for next ESR version bump.
