Though it changes the colors of the site, it's not really a reader; tiny text remains tiny. It's just a dark theme. Also, the dev tools button doesn't work.

Awesome but on Firefox Nightly for Android, there is a few seconds long delay applying the dark theme when a new site/page is loaded, which means constant flashes of white themes.

Thank you it's so much easier on my eyes.

Amazing. Just what I've been searching for for ages!

Makes the new tab page white which is very annoying. Otherwise great extension with lots of customization.
