Like I know he doesn't really know us (his supporters) but you'd at least like to feel respected by him. That he understands that this Epstein thing is a big deal and he will find a way to redact the stuff he is uncomfortable with and give us the rest.

Toasting in epic bread!

How to disable the full screen transition in about:config:
full-screen-api.transition-duration.enter 0 0
full-screen-api.transition-duration.leave 0 0
If you want to disable the "example.com is now full screen" message too:

full-screen-api.warning.timeout 0
I prefer to leave the warning on as it is apparently an anti-phishing thing, but I hate the black screen transition.
