Perfect. Makes Firefox look good again.

This theme improves the usability of firefox by making the selected tab easier to see. In screens with bad viewing angles, the active tab in Proton is much harder to see.

I wish more themes behaved like this one.

I find latest firefox default theme hard to see current active tab. This is a life saver!

This FINALLY fixed the problem I was having with selected text becoming invisible (or the same color as background, regardless of whatever background color was selected) on my 94.0.2 updated Firefox. MUCH better, back to its old reliability!
