After finally receiving the Nova update, I found the default theme options no longer suited my needs. Thankfully, this theme accomplishes that with ease! It's a simple, solid color dark theme, which doesn't bring attention to itself. The Firefox UI shouldn't take visual priority over the websites I'm browsing, and this understands that philosophy very well. If you feel the same way, you'll probably like Matte Black too.

This worked well with my CSS script, getting rid of all the ugly features that Nova introduced. If I wanted my browser to look ugly and childish, I would have bought an Apple device. Thank you!

I've been using firefox' default design for ages, but the menu bar gradient in the latest redesign is really distracting to me (and sometimes, the colour gradient blends in with the favicons in the tabs, thereby making them less recognisable). So I've been locking for an alternative in a simple, monochromatic design, and this is perfect! Thank you!

nice and clean

Used a blue version for many years without realizing a clean version exists. Very good, I wish it also existed for Thunderbird.

nice

Clean, sleek, awesomesauce.

Thank you for addon works fine...

Perfectly integrate with gnome dark theme, looks great with firefox window maximized.
