The black fade animation when exiting fullscreen is roughly the length of
the anti-clickjacking delay on permission prompts. It was possible to use
this fact to surprise users by luring them to click where the permission
grant button would be about to appear. This vulnerability affects Firefox <
120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.
