Ditto! Firefox 102.0.1 (64-bit) on Windows 10 Pro (64-bit) with all updates applied.Yep, I'm not having any problem with FF in full screen mode, move to the top and the "missing" buttons show up like magic.
1) Hit [F11] to get Firefox full-screen
2) Move the mouse cursor to the top of the screen and the top bar (sans the Bookmarks) that disappeared when I hit [F11] suddenly reappears.
