With Proton, I could finally fully appreciate this theme a lot more. Why? Because it's easy to see your current tab plus it looks great. I love the color choices! Although font color for the url bar is very difficult to see. When using other themes, sometimes the sound icon on tabs can be hard to see, but with this theme, it's easy to see. If I have any other complaints (and now I'm being nitpicky), it's that the Firefox home page isn't dark.

My favorite theme. It took me a while to find it again after I mistakenly deleted all my extensions. Really glad I found it

While the top and bottom look amazing, the bookmarks bar is a glaring white, as well as the new tab page. Doesn't fit with the rest of the theme unfortunately.

Perfect, although I would suggest making the toolbar slightly less transparent, as certain extensions seem to blend in, and look almost invisible.
