What 7 buttons are you referring to?

rt click anywhere on the tab bar to access the Customize toolbar page. Lower left you can uncheck Title bar to rid yourself of the top bar. Some users like that title bar - quite a few.

If understand your complaint: You have added many buttons to the Menu Bar and these are pushing the three (mimic) system buttons too far to the right.

First, unlike the main toolbar, the Menu Bar does not have an overflow menu feature like the main toolbar. I don't know whether one can be added.

Second, as a workaround, you can use Alt+Spacebar to call up the window control menu with the same options as the 3 buttons.

Other information

Firefox 141 changed the three mimic system buttons that normally appear on the right end of the tab bar when tabs are in the title bar, or at the right end of the Menu Bar when the Menu Bar is enabled. Previously, the buttons were drawn with images, and now they are drawn with fonts. Just in case you need to review the CSS to adapt your rules in the future:

I'm referring to the menubar. The second image shows the buttons in the first image, those 7 items, that were forced off screen to the right.

Just for the sake of conversation, is there a reason why they would allow that to happen. Is there a purpose?

Yes. You taught me something that never occurred to me. There is no "Pin to overflow" for the menubar. Why not, I wonder. You can place any button on either toolbar. Also, there is a limit to the number of buttons that can be place on the main bar, that will be visible, but not the menubar.

Probably not enough people have expressed interest. The menu bar is off by default on Windows, so I assume most people do not use it, and even fewer people use it as a button bar.

I did see a bug the other day related to this problem, and the result of fixing that might be that your excess buttons are hidden so you can still access the system buttons.

Right now the min/max buttons are showing on the upper right, about my tabs. But in the last ?couple months? they disappear when I am on some sites & it's been driving me crazy. I'm glad for the tip of Alt+spacebar, but better would be to know how I can avoid this happening at all. It doesn't matter how many tabs I have open.

Do you have the Title Bar or Menu Bar showing, that's why the buttons are above the tabs?

Is there any pattern to what sites show only a close button?

If you use custom style rules in a userChrome.css file, those might need updating from time to time.

I seem to notice it often after I have Facebook opened. But right now it was missing when I first opened Firefox. Then I had to do Alt+space to find my screenshot tool, so on the screenshot attached it looks present. At least you'll be able to see what my top setup is. When I have a problem, that entire white strip across the top is missing. I don't see anything in Settings to allow me to show/hide titlebar or menubar. I don't know enough to do any .css changes.

You can turn the Title bar on and off using the Customize panel: Customize Firefox controls, buttons and toolbars. There's also a Toolbar's popup there is you want to see what the Menu Bar looks like (but it's not turned on in your screenshot).

I can't think of any reason that Facebook would affect the controls on your toolbars. It's not flipping to full screen, which removes all the toolbars?

I'm starting to understand this a little better, been doing some experimenting. So the white line on top is what you call a "title bar". And when I have the title bar turned off the min/max button moves down to the area along which the tabs display. I tried adding the Full Screen to my tool bar & learned what it does. I previously thought that when Firefox was at Maximum that would be the same as full screen. Apparently not. But seems like something must be triggering Full Screen because that is not a function I knew how to do. My laptop screen sometimes has problems showing me the whole page because of the width to height ratio, so I do "CTRL -" the zoom on occasion. Maybe something about that? ETA: And I just remembered that my laptop sometimes acts on gestures even tho I have them turned off. Mostly it just changes my zoom.

I'll try to pay attention in the future.

Thank you so much for your help. My first attempt on the forum & I never really expected to get such quick & relevant answers. Definitely not AI !!!
