Thanks you!

Love the addon, but Firefox claims it is corrupt. What gives?

I like it it works but now Firefox has remove it and will not let me down it again They will not let me down load any thing !!! What is wrong ?

Perfection! I tried a bunch of dark theme extensions but Dark Reader is the only one that works perfectly in nearly all websites. It just gets confused with the dark theme from Firefox.

In Firefox for Android it's the only app that allows me to make all websites pitch black to save battery in my AMOLED phone. So so good.
