Cannot disable fullscreen animation (F11)

Hi, I'd like to disable that annoying animation when going to fullscreen (by hitting F11). Supposedly, setting the following should work:

Go to about:config

Set: full-screen-api.transition-duration.enter 0 0 full-screen-api.transition-duration.leave 0 0 full-screen-api.transition.timeout 0 full-screen-api.warning.delay 0 full-screen-api.warning.timeout 0


However, this does not have any effect in Firefox 94.0 on Ubuntu. Is this a bug/regression? Or is there some other way to disable the animation?

PS.: I also have toolkit.cosmeticAnimations.enabled = false, to no effect as well.

Note that toolkit.cosmeticAnimations.enabled isn't supported for quite some time and you can reset this pref (click the trashcan).
