Fix the tab bar (and other stuff) in the new Firefox 57

Firefox 57 – also known as Firefox Quantum – was released recently, bringing all the glorious new performance improvements to the world.

Well, that’s nice, especially if you pronounce “Firefox Quantum” in a Mr. Moviefone voice… BUT…

The new version of Firefox also includes a “better” tab bar, which is supposed to be better than the old one.

There’s a problem: by default, it kind of sucks.

There are also a few other (annoying) changes.

Fortunately, it’s pretty easy to fix most of these problems…
