Неплохо но замедляет скорость обновления страниц в Firefox как на ПК так и со смартфона, это минус.

It works every time

It works well on majority of websites. But sometimes images on some websites don't blend in with the darker tone and creates a bad experience

very nice & smart dark color style, suitable for almost all websites.

----
except that it modifies the firefox tab bar look, which deactivate my firefox theme.
// It would be nice if has option to disable this feature
// using in ubuntu20 darkmode, firefox 96

Bug: I use 64-bit firefox from Microsoft Store, this extension cannot follow the windows color scheme，always maintains light color mode

This add-on works with google maps, Amazon, and basically all the websites I use daily! And dark mode is done very tastefully. I'm really impressed.

Just too slow, too much delay. Not worth it overall.
