If watching any video in full screen, upon restoring Firefox back to "normal view" the entire program changes its position on my monitor.
In regular mode (IE; not full screen) the position of the program on the screen - flush with my top and bottom panels - but NOT full screen is unaffected when closing and re-opening Firefox.
The change in screen position is only when going from full screen view to non-full screen mode.
OS: Ubuntu MATE 22.04.4 LTS 64 bit
Firefox Ver: 115.14.0 ESR 64bit
Hopefully someone can help.
Cheers
