Up until recently, I've been very happy with it, but something in Firefox changed, and now FF complains that this extension is slowing everything down and causing timeouts.

I wish it darkened Google Docs and Google Classroom. Glitches Drive main page

Some elements are not included in the style: search bar, links, footer...

The add-on somehow interferes with google images right side search results causing them to glitch out.

Ela realmente faz o que promete, só que tirei duas estrelas por que no menu na extensão tem opção de escolher a cor de cada item separadamente, como cor da fonte, da seleção etc, mas mesmo clicando em salvar não funciona. Ele não salva e qd vc volta no menu está ainda do mesmo jeito como se não tivesse salvo. Mesmo mostrando a msg dizendo que suas configurações foram salvas ao clicar em salvar.

not works after restart browser

Top, même si il y a un quelques petits problèmes concernant les images apercu quand on fait une recherche, et également je me demande pourquoi ils ne l'ont pas activé aussi sur le YouTube. Dommage.

last update made the colors inverted and not black as it used ,it was perfect i don't know what happen =/ ,would be great if can be fixed ,thanks !

It's okay but screws some things up such as the timer function and Google Maps. https://imgur.com/eQ1BxDf.png

Useful for image search, as some other dark mode extensions prevent images from displaying correctly.

The description in Add-ons manager states that it works for translate and contacts; for translate it looks bad, for contacts it does nothing. Also I'm seeing the corner of the Youtube logo showing up in the Apps menu icon.

It works very well but the only problem is that it makes your https turn to non secure. The lock icon turns grey.

Doesn't work for Google News

Great add-on, but in google contacts, when you open the single contact window, it is transparent and you have contact list in the background and it's a big mess

It's easily a five star addon but once it's on it turns your https as insecure due to an images conflict which obviously needs a fix.
