This extension is just to change between light and dark versions of the theme, if you just use dark/light you can find it under themes in his profile.

Nice job ! I use the Dark theme.

not sure why it's not visible in "themes", but i think that's some firefox limitations here. awesome themes.

Dear Dev! The best theme here, glad I found it and thank you for your work. But it can be even better if you fix white theme colors. Please, check the tab bar grey color, grey gives off very yellow and green, what is associated with disease and infection. If you change it to clean grey color it ll be much better! thank you for your attention!

The only Light theme I will use coupled with a nice dark theme; both are toggleable. Coupled with the creator's userChrome.css and a few of my own tweaks, it's a minimalist dream. Thanks Dumindu!

Just. Beautiful.

Thanks a lot for making and sharing this Dumindu Madunuwan!

OMG! This is beautiful!

It is the best extension what I ever seen, if compare with usability, result and requested permissions.

I love this so much. Really clean and beautiful - thank you

This is a great theme. It will match well with macOS Mojave's Dark Mode.
