Necessary add-on! Just what I need to avoid all those sight killing white pages.

how do I configure different colors on different pages?
Thanks

I have used this add-on for years now. It allows me to work in front of a computer for hours (it saved my eyes). I use it on a Windows laptop, a Surface Pro. I also, added to my desktop computer at work. Terrific contribution to mankind! Thank you Mikhail.

Best addon till date.....has been using since 2017..

大概のウェブページをダークモードで表示してくれる。また、ページ単位で簡単にオフできる。

Excellent until now. Mozilla says it's broken so please mr Khvoinitsky help!
Personally I can't read with white background so this is difficult to say the least.

Well done, Mr Khvoinitsky! I like the use of the wheels to tweak my color selections. Used in conjunction with 'Redshift' (linux program), have adjusted the color temperature of my screen to 1900K. Now as easy on the eye as candle-light. Big thanks!

very very good.

Some of the other addons in this category turned out too buggy. This is my absolute favorite addon for reading online. My eyes are very grateful.
