When I watch long videos in Firefox (ex: videos on yewtu.be), the screen turns black while the video is playing. I would like that this doesn’t happen when I’m watching videos, while keeping the functionality of auto-locking my computer when idle while not watching videos.
Ideal solution: My computer would blank screen and lock (ask for passwork) after 10 minutes of inactivity except if I’m watching a video.
Context: This happens when I watch yoga instruction videos or meditation videos, so I cannot shake the mouse every couple minutes to prevent the computer to idle because I’m far away of the computer.
What I tried so far:
- I read this topic and tried various combinations.
- In Power Management Settings, I tried to enable/disable Idleness Watcher.
- In Screensaver Preferences, in the Advanced tab, I tried to enable/disable Power Management as well as Quick Power-off in Blank Only Mode
