It slows up almost everything. I dont know why its recommended really. Makes FF too sluggish and slow when you open new sites or change from tab to tab.

As a teacher, this was great app ! thanks!

It's great! just wanna ask.. can this extension have more option such like disabled the theme to be changed because I am using firefox color and after I am using this extension it's always change the theme to and it's not have the firefox color extension theme to be come back!
I just wish it's not being changed or anything that's all thx!!

Edit:I just found the option I thing I'm not seeing it before sorry! I found it in the bottom of more section, thx for including this features!!!

This addon used to be great. now its only 'this extention is slowing down this page' error. when i deleted the extension, sites opened within 1 second again. so by default this addon slows down loading.

Best dark theme add-on I've used. Pleasant visual design of the pages.

Dear developer, please check time scale on youtube because it darks and users can not see seeking time. Thank you for amazing app
Update: I turn off this extension on youtube page and you dark mode by youtube - itselft. Everything ok
