How to Disable Animation While Going Full Screen in Mozilla Firefox

Whenever you go into Full screen mode in Mozilla Firefox by pressing F11 key, the tab bar and toolbar go up with animation.

Some people might love it but many people may want to disable it to launch Full screen mode faster as the animation takes time and slows down entering into full screen mode.

In this tutorial, we'll tell you how to disable this animation:

1. Open Firefox and type about:config in the addressbar and press Enter. It'll confirm, click on I'll be careful, I promise! button.


2. Now type animate in the Filter box and look for following integer key:


3. The entry "browser.fullscreen.animate" would be set to true. Double-click on it and it'll change its value to false. Alternatively, you can right-click on the preference and select Toggle option.

4. Now whenever you go into full screen mode, you'll not see the animation.

  • Thank god! That horrible/slow animation was driving me crazy while using youtube.

  • The little momentary 'laaaaging' TIME created by those useless "animated effects" may only add maybe a short "half a second" or so of extra 'lag-time' to your Windows experience. But THAT is still more than enough time to drastically inhibit ur groove & TRIP UP your otherwide GRACEFUL SMOOTH working FLOW! Every little pause effects your ability to maintain a steady GROOVE like being in the ZONE. Its is a lot like how a heavy ball gets rolling, and it builds up momentum & speed & "gracefulness" comes along with it as you go......................all up until some DUMB-@#&$ useless system property wasting ANIMATED CRAP has to trip you up & get in the way of an otherwise SMOOTHER, NICER DAY! DAMN U PROGRAMMERS!!!!
    (((DEEP SIGH)))
    Wheew... I feel a bit better now. (smiles) You see everyone, sometimes I just have to "VENT" at something, even if its something relatively insignificant, just to help release some of the built up STEAM from other areas in life! : )
