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

Question

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:

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

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All the other the resources I found on the Internet were outdated (they suggest modifying options in about:config, which no longer exist).

Unfortunately this doesn't seem to work in Firefox 77.0.

This is no longer the answer for the "newest versions of Firefox".

Hmmm, I've got all those set to zeros, but it still does not disable the animations for me on Firefox 83.0.

This disables the fade-to-black transition that happens when going fullscreen with the Fullscreen API, but has no effect on the UI element animation that the question is referring to.
