@debiedowner said in Do not dim the entire Picture in Picture (PiP) video on mouse hover.:
this annoying behavior is inherited from Chromium
Yes, i discovered this long ago with my Chromium [in Linux]. I hadn't checked for a while so did it just now... still dims PiP window on hover identically to V. By contrast, Firefox PiP does not dim the PiP window contents at all, but elegantly makes the controls become visible on hover, then vanish again when unhovered [Patent Pending TM].
Firefox handles this very well. I've sized and positioned the pop out video once, and now every other one is correctly positioned. In the off chance that I'd like to change it, I can, but 99% of the time it's already where I want it to be. The current behavior has it sized and positioned in a way that isn't very useful.
We could also potentially have a setting for Remember Popout Window Settings: Globally, Per Website, or None.
