Firefox Picture-in-Picture (PiP) Issue

  • Problem: PiP window loses "Always on Top" focus or vanishes when switching workspaces/tasks.
  • Config Changes: Set 'focusmanager.testmode' to true and 'media.videocontrols.picture-in-picture.video-flips-visibility-on-focus-change' to false.
  • Window Settings: Focus set to "Click" via GNOME Tweaks/Settings.
  • Environment Test: Tested launching via 'MOZ_ENABLE_WAYLAND=0' to bypass Wayland focus logic.

Software & Tools

  • Tweaks: Installed for font hinting (Slight) and window behavior management.
