Can you please confirm if you have enabled the 'Menu Bar' to be visible on the browser. Also, please check if this support article helps you Tabs in Title Bar

Here's a screenshot of Firefox on my computer. Since I'm on Mac, there is no actual menu bar since it is built into the Mac OS. Essentially, I want the tabs to be where the page title is, if that's possible.

I am not 100% sure, but I don't think that is possible. I will let other Mac users in the forum respond to you on that.

Okay, thank you.

If anyone else on Mac was having this issue, what I did was download Firefox Nightly which uses the theme that future Firefox versions will use. Keep in mind that Nightly is basically a beta version of Firefox, so there is the possibility of issues arising.
