It's good, but it lags the browser a lot. Especially if you're the kind of person to keep a lot of tabs open...

Worked great for a long time. Then a new update came out and it broke everything. Pages don't load properly anymore and I couldn't find any solution. Hope it gets fixed soon!

Seems to slow down a lot of websites when activated. Twitch especially.

this extension solves a surprisingly hard problem surprisingly well. It just works.

Black out the EARTH. Thank you.

Does not save settings. Always reverts back to "dynamic", which breaks a lot of sites. Changing to static or anything else is not saved. It's nice for a month or so, but after you have to disable it for the 20th time just to get something done because the settings aren't saved, it gets old. BROKEN ON FIREFOX. Still works on chrome though.

does it's job perfectly. firefox must include some addones in it by default and ask the user on installation a fresh copy whether or not you want to enable it

Works like a charm.

So far, every website I tried it on worked very well, and the customization available is very nice: color, contrast, eye-strain reducing sepia tinting, white- and blacklisting websites are all available.

I am very happy with the addon.
