After the lastest update, every time I put a YouTube video on full screen Firefox does a fade out and fade in effect that, for some reason, annoys me A LOT. Is there any way to remove it?

Chosen solution

Try to modify these prefs on the about:config page. Leave out the quotes around the value (enter only two zeros separated by a space).

  • full-screen-api.transition-duration.enter: "0 0"
  • full-screen-api.transition-duration.leave: "0 0"

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
