Hello,
On Mac OS when in fullscreen, regarding the top bars: the menu bar (apple with traffic lights) is NOT tied to the tab, URL, and bookmark bar which makes the UI very clunky when navigating the bars at the top of the screen, because the menu bar appears when the mouse reaches the top edge of the screen, and disappears when trying to click on a tab, the URL bar or the bookmark bar, which makes everything shift and makes it easy to miss click.
Google Chrome for example ties them all together, so they appear all as one, so the menu bar stays visible as long as mouse is over any of the bars, which keeps their position stable while navigating any of those bars, and they also disappear as one.
I cant reprogram this without changing firefox from the ground up.
Please change this behavior to exactly how it functions in Google Chrome since it's objectively better - but Firefox is objectively better at everything else (keep the scrolling and size behavior of the tabs, privacy settings etc - you are doing great!).
Thank you for considering this, and maybe even getting back to me!
Kind regards,
ManWell
