This looks like a problem with your system setup or so. From the log: ``` [Parent 13156: Main Thread]: D/LinuxWakeLock [7f5ce86424c0] WakeLockTopic::DBusInhibitScreensaver() [Parent 13156: Main Thread]: D/LinuxWakeLock [7f5ce86424c0] WakeLockTopic::DBusInhibitScreensaver() proxy created [Parent 13156: Main Thread]: D/LinuxWakeLock [7f5ce86424c0] WakeLockTopic::DBusInhibitSucceeded(), mInhibitRequestID 16 [Parent 13156: Main Thread]: D/LinuxWakeLock [7f5ce86424c0] WakeLockTopic::ProcessNextRequest(): recent state inhibited [Parent 13156: Main Thread]: D/LinuxWakeLock [7f5ce86424c0] WakeLockTopic::DBusUninhibitScreensaver() request id 16 [Parent 13156: Main Thread]: D/LinuxWakeLock [7f5ce86424c0] WakeLockTopic::DBusUninhibitScreensaver() proxy created [Parent 13156: Main Thread]: D/LinuxWakeLock [7f5ce86424c0] WakeLockTopic::DBusUninhibitFailed() UnInhibit call failed : GDBus.Error:org.xfce.PowerManager.Error.CookieNotFound: Неверные данн ``` So we got inhibit ID 16 and used it for uninhibit but it failed. Doesn't look like a Firefox bug. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/2047262 Title: Firefox stopped inhibiting screensaver on video playback Status in Mozilla Firefox: Confirmed 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.
