about:config browser.fullscreen.animateUp has no effect
My original problem: I wanted to stop the molasses-like animation pulling the browser tabs and navbar off screen when I press F11. Unrelated to the fade-in/fade-out with fullscreen videos (which I'd already fixed).
I saw the preference browser.fullscreen.animateUp described in http://kb.mozillazine.org/Browser.fullscreen.animateUp and mentioned in https://support.mozilla.org/en-US/questions/1066680 . This seems to be what I'm looking for, or it used to …
My about:config did not have this preference by default. I added a preference with the proper name and tried setting it to string values "0", "1", and "2" and integer values 0, 1, and 2 with no effect either immediate or on Firefox restart. That is, the F11 animation did not change. After refreshing my Firefox through Troubleshooting Information, I tried all six again with still no effect.
Chosen solution
Maybe try to set this pref to false:
- toolkit.cosmeticAnimations.enabled = false
Some reading:
- bug 1352069 - Introduce a pref that allows for disabling animations (toolkit.cosmeticAnimations.enabled)

You can modify these prefs on the about:config page to disable the full screen fade in and fade out. 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.

Thank you, cor-el, for your answer. However, as I said in my question, my problem is "Unrelated to the fade-in/fade-out with fullscreen videos (which I'd already fixed)." It has rather to do with the dragging animation when entering fullscreen using F11 when, for example, Firefox is open to a local TXT file.

Setting
- toolkit.cosmeticAnimations.enabled = false
did indeed solve my problem. Thank you for the answer and links, cor-el!
You're welcome.
This was new to me as well.
