It saves my eyesight.

I got a popup in the addon that links an article, decrying Russia's operations in Ukraine. I didn't install a simple dark-mode addon to be bombarded with more political nonsense. I just want to be able to use my addon in peace, for god's sake.

The best!

Very Good for someone with Insomnia & Seasonal Depression, keeps my rhythms in order.

Its Mozilla addons description page claims it "doesn't show ads" but when you go to its options page, it is absolutely slathered with advertisements for "sponsors" (i.e., the developer has been paid money by these sponsors to put this advertisement there). Extremely dishonest.

the dark theme can protect eyes efficiently,and I don't find a greater theme addon yet.

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

Noticeable lag upon clicking a website so i deleted this extension within 5 minutes of using. I am instead awaiting a global native universal dark for all websites, hope Firefox implements this like Chrome's "chrome://flags/#enable-force-dark" which is extremely effective on all websites and without the slowdown of an extension.

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
