Title:
Firefox stopped inhibiting screensaver on video playback
Status in Mozilla Firefox:
Fix Released
Status in firefox package in Ubuntu:
Confirmed
Bug description:
Update (02/2024):
With Firefox 122 on Ubuntu-Mate 23.10, screensaver/powermanager inhibition is
completely broken even with Mozilla's .deb package.
After a fresh start of firefox, screen saver is blocked properly when
playing video but after opening/un-suspending a few tabs with video,
inhibition stops working.
I was unable to come up with reproducible scenario but after a few
hours of browsing it usually stops working. Restarting firefox fixes
the problem.
The bug first appeared around August and affects both .deb and snap
packages.
Tested on Ubuntu-Mate 22.04.3, Xorg, both Pulseaudio and Pipewire (if that's
relevant).
I don't see any relevant msgs in xsession-errors or system logs.
