How can I disable animations in Firefox when going full screen?

I would like to disable the transition animation when I hit F11 to go full screen on Firefox.

The animation slowly pulls up all the tabs and bars off the screen instead of immediately hiding everything.

In the newest versions of Firefox:

1. Open the about:config website
2. Set toolkit.cosmeticAnimations.enabled to false

Tested on:

• Firefox 57.0b9 (32-bit) from the Debian experimental branch running on Debian testing (buster)
• Firefox 56.0 (64-bit) running on Ubuntu 17.10
• Firefox 68.0 (64-bit) running on FreeBSD 13.0-CURRENT

References

• about:config browser.fullscreen.animateUp has no effect (support.mozilla.org)
• All the other the resources I found on the Internet were outdated (they suggest modifying options in about:config, which no longer exist).
