Breaks the least amount of websites and has the least performance impact, at least in my experience. The stylizing is also pretty tasteful and reasonably true to the original pages. I did like the function/appearance of Midnight Lizard even more, but it was just too resource intensive.

wow 1 ère fois que je ne trouve rien de négatif a dire sur un plugin thème tout simplement parfait tout les éléments des sites web s affiche selon les paramétres choisi travail de maitre !!!!

Great extension, but with some minor issues.
I set up a black squat theme on Firefox, but every time I restart my browser, Firefox's main page will change back to bright. I think this is caused by this extension, I hope you can fix it, thank you!
In addition, in the search engine of Baidu(www.baidu.com), it only works on the first page, and all following pages are changed back to bright.

I think this is the best add on for changing web page color :D

I like very much the keyboard shortcut resource. Thanks!
