The only one that worked on android. It's good!

Works really well on my Samsung galaxy Tab 10a in combination with normal (white) webpages.

It works and makes the bar black. However the text stays black. So it's basically black on black which doesn't work very well

Seems to work, although I have to leave Firefox then come back. I think that's a general problem with Firefox, not this theme.
Would be better if the bottom navigation bar was also dark.

Would be perfect if the icons were white.

What a simple working black beauty of a theme this is for mobile version of Firefox.

A dark Firefox address bar and a black Android status bar. If you're looking for a dark mode experience, this is as good as it gets.
