Firefox 150.0.1 profiles menubar on macOS

[ffperson]

Hi Firefox community,

In the recent update to 150.0.1 on macOS there's been a change to the menu bar that's been bothering me. The previous menu bar is still accessible within the "About Firefox" window:

And this is the new menu bar, when focused on the main Firefox browser window:

The font spacing is much larger in the bottom (between History and Bookmarks) and the addition of the Profiles button makes the menu split. This is more of a problem with the OS, but personally, I don't use profiles and would rather access them from the hamburger menu than take this much room of my top bar and compete with my systray icons.

I didn't know if I should post this here or file a bug report, but any advice on how to revert this would be great.

Hello

For information, a subject https://www.reddit.com/r/FirefoxCSS/comments/1sr35j2/ff_1500_a_new_profiles_menu_appears
You can try, install userChrome.css https://www.reddit.com/r/FirefoxCSS/comments/1sr35j2/comment/ohc2xf9 in all profiles

I tried the solution from that thread and it doesn't seem to work on macOS. I'm going to use Firefox ESR for now and make a report on bugzilla after I try finding what happened in mozregression.
