Had this dark background for years. It the only one I use that's easy and does what its supposed to. I especially like that it highlights text. I like to go through videos from channels I like on YouTube. With this extension if I have seen this video it highlights the video title so I know I have seen this video. It does it in other areas also but that helps alot and helps me keep my place in different sites and areas. The only problem is that ESPN.com doesn't work well with this extension. It screws the page up unless I do some maneuvering and even then it doesn't always work. If it could work well with ESPN it would be perfect but I have to disable it on there. Great extension though. If the ESPN situation changes then I can give it 5 stars. It looks good and works almost as good.

finally found the perfect dark addon. lightweight and functional

please make side options for emojis and other characters under "invert" mode.

Excellent add-on. My eyes feel better already!

This is wonderful. My eyes have problems with white backgrounds and white on black is also problematic. But I was easily able to set it to a light grey background with black print. Now, if only it would work on non-browser pages (e.g. Excel, Word, all Windows 10 menu pages... that would be heaven!)
By the way, I ticked the box "Do not set "Override Document Colors" to "never" (not recommended)" which, with its double negatives means "set it to always".
March 15 2025: Firefox (on my PC) has disabled this app and I cannot download the latest version because I am being told "it appears to be corrupt". :-(

Gave everything adwaita colours, you're next.

Works great!

Works amazingly well. Some sites don't look right with the colors but it saves my eyes.

not good
