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
