Is is really a very useful addon, the only problem with it is that it slows down page loading. It is painfully so sometimes. Works better under chrome, i hope the developer will cope with this problem under firefox, too.

It's not perfect, sometimes I have to disable it on a page to fix errors and sutch. But it works fine for most sites and I don't like browsing without it.

Perfect! Reduces eye strain and probably reduces electricity consumption.

there is an all white time when load the slow website body,after that this DR works,please fix the shining eye

Very good look and feel on almost every page. This is however very CPU intensive (for example on Twitter.com)

good first impression

Excellent pour la lecture nocturne et protège les yeuxde la lumière intense de l'écran.

it's odd because on some specific website it will pop a tip which writes "darkreader is slowing your website", and then the firefox stuck for a while.
Besids that issue, it's pretty good add-on.

Works really great most of the time, good enough otherwise. Eats CPU time, enormous amounts. Worth it, anyways.
