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.
