For me, it only works on the tabs pane, sites remans the same

I like this addon, but I really want an option to use it on restricted websites.

Its a good addon, but it automatically turns my custom theme black, which is why i did not rate it 5 stars.

If the option to leave the theme alone appears, ill fix this rating to a 5, but otherwise, it gets a 4.

Let me have my stary pixelated theme god damn it >:T

life-saver for my retinas, HOWEVER
costs a LOT of ram. if your browser lags hard i gotta go to task manager, firefox and kill the sub-program trying to eat 12gb of my 32 ram. usually works for long enough until i gotta repeat 10-15 mins later

Works well on most websites, with or without tweaking. Prevents flashbangs even on "dark-themed" sites.

I *really* want to like this extension. It's got a lot of promise. But it's a huge resource hog, at least on my system. I have to fiddle with it on any site with even slightly fancy styling, so I can't really justify the performance dip. I tried switching to a CSS injector with some basic rules and it was more reliable and efficient than this. I hope (and have faith) that'll one day change, but for now I can't use this.

good

YEEEES lets go

A must have, it used to be paid before after a certain days (or maybe it still is on chrome) but now its the best browser extension to have, and works like a charm almost every time

I installed this extension on Firefox for Android, YouTube will not play frequently and I had to restart Firefox frequently. I didn't know this, so I suffered this inconvenience for 1 year and 5 months.

Awesome but fails to overlay settings (additional darkening) on Google search pages. This doesn't happen with the Chrome version of this extension.

Made my YouTube lag while I played games. Very Irritating be warned had to uninstall.
