Firefox fullscreen optimizations

Saturday, January 16, 2016 » Firefox

Firefox has some quite annoying features for fullscreen display of HTML5 videos. This is howto disable those in about:config:

Disable fullscreen warning:

Set

full-screen-api.warning.timeout to 0

and

full-screen-api.warning.delay to 0.

Disable fade in and out animations:

Set

full-screen-api.transition-duration.enter to 0 0

and

full-screen-api.transition-duration.leave to 0 0.
