In fully updated Windows 10 (x64), running either 64-bit or 32-bit Firefox, the tab bar in the current Release channel of Firefox disappears. No changes have been made to the Firefox profile on my computer, including no edits in CSS, etc. (I never bother with such things). Updating to 108 and higher causes the tab bar to disappear. In 108+, a single tab appears "somewhere" at the bottom of the window (its location appears to be random), and the New Tab button ("+") is gone as well. Disabling all extensions has no effect. Reverting back to 107.0.1 (either 32-bit or 64-bit) fixes the problem. This situation has been tested several times with the same result every time. Consequently, I have edited the Firefox registry policy to disable updating so I can run 107.0.1 without constantly getting the Firefox "nag window." Any thoughts on this problem would be greatly appreciated.

Looks like you are using userChrome.css in the chrome folder in the profile folder to move the tab bar and this you need to update of the CSS code. More info about userChrome.css/userContent.css:

For tabs below the nav-bar code update for 108+, see:

I checked, and to my surprise there was indeed a chrome folder in my Firefox profile. I don't think I've done any CSS editing since Firefox 35 or so, so I simply deleted the chrome folder, turned Firefox updating back on, and updated to Firefox 110. The tab bar is now working as expected. I must've pulled userChrome.css over onto my current computer when I updated hardware in 2016! Thank you!
