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.

Ditto! Firefox 102.0.1 (64-bit) on Windows 10 Pro (64-bit) with all updates applied.

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.

I have not ever seen a problem with Fullscreen mode.. and also can, with the cursor/mouse, shut down with top right buttons.. but I am of the opinion too many seem to totally rely on the mouse for control... My wife is legally blind.. and we have a 32inch screen for her with very large font set up.. She cannot see the "buttons" at top right, and even my Custom bright orange mouse cursor(Very large) is difficult for her.. so she is now filally learning the keypresses needed for getting out of things, closing windows, etc... and various other useful things... So to be as lazy as to expect the mouse to do everything is just that... Earlier it was stated... F11... well, how do you get into Fullscreen mode? I have never bothered to look for a Mouse-led command... just F11.. both in and out.. using a mouse requires a lot more effort.....unless you don't have working arms!!

I am using 102.0.1 also, on 11, not 10, and with no real issues so far.

Well, with no arms the keyboard is more of a challenge as well!

Howdy everyone, just back from vacation. I made this screen shot to dazzle everyone who thinks this is somehow imaginary or impossible. I assure you it is quite a real nuisance. Tomorrow I will try some of the tips left here. My thanks to you all.

If the video is supposed to show the original problem then I'm 90% sure it's an add-on that's causing it.

Okay, I'm running ghostery, ad blocker ultimate and tampermonkey with a youtube sign in script running. So far I have switched off all three and doesn't seem to make any difference. I was running all three of these for a long while before this problem cropped up.
Thanks.

Look at all your FF plug-ins, themes and extensions. I'll bet there's more than you mention.

How to Start Firefox Without the Add-Ons

How to Start Firefox Without the Add-Ons. Add-ons in Mozilla Firefox automate a wide variety of tasks and enhance the functionality of the Web browser. Too many Firefox add-ons slow the browser dow, however. Add-ons also occasionally limit the functionality of websites or even block websites...

The entry described doesn't exist in that menu.

 

[SpywareDr]

Okay, then try clicking Firefox's Hamburger Menu (three stacked horizontal lines) over on the right, then Help > Troubleshoot Mode > then click the blue Restart button on the pop-up that looks like this:

 

[Corday]

Or Help>Troubleshoot Mode from the Menu Bar.

 

[SpywareDr]

(There's an echo in here. )

 

[Corday]

(There's an echo in here. )

No. My way skips the "Hamburger"

 

[SpywareDr]

Ah yes but, you'd have to enable the Menu Bar before doing that. The Hamburger is always there, either way.

 

[Corday]

I'm old fashioned and have Menu Bar enabled in all my browsers.

 

[SpywareDr]

And yet another way is when you don't see the File Menu at the top, press [Alt][H] to bring the Menu up with "Help" highlighted, then hit [M] for "Troubleshoot Mode".

 

[Corday]

Well this is fun. How about in Command Prompt>C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode or start firefox -safe-mode depending on version.

 

[SpywareDr]

Yep, that's also good one as well. Many are leery of a CMD prompt window though.

 

[johnwill]

My point was that the original recommendation for that troubleshooting page was incorrect. I don't have to start in debugging mode, I don't have a problem.

 

[SpywareDr]

Yes John, got it. I take full responsibilty for grabbing the old instructions I had, which are now deleted.
