One of the best dark mode extensions (along with Sauron, another great one). 5 stars. The following are my reasons:

1. Much snappier than all the other similarly principled extensions I've tried (including Dark Reader & Midnight Lizard, both of which are so... insufferably... slow...)
2. I have not encountered white blinding flashes (yet?) in-between opening new tabs & loading new pages. Dark Reader does this a lot & it is absolutely terrible. Midnight Lizard does this sometimes as well.
3. User friendly in terms of managing preferences.

just a top add-on!!! 👍🏻👍🏻👍🏻

Really good extension but none of the profiles work well with google docs. The default will make the cursor almost invisible. Invert makes the cursor visible but will make the colors of photos inverted as well.

I love this extension, it's usually the first one I install, & should be incorporated as a standard feature of ff ( along with vertical tabs in the sidebar & per-page RAM deallocation ). Its only complication is that ( on slower machines ) it can't execute before a loading displays its white background ( caused by ff not this ext. ). ( Extensively tried in Linux & Windows10 ).

And it doesn't pilfer my private data. Viva la libre!

Does JUST what is is supposed to do, dark background, Light text... & the BEST thing s you can see the 'buttons', Options, etc. highlighted, not 'buried in the background... THX MK !! (although, I wonder why, isn't it, working on this Mozilla page)?

nice layout

Thanks Dev, this is a great extension.

I especially like the way that custom colours can be added.

Saved my eyes! Love it.

Does exactly what I wanted. Only thing that could improve it would be to eliminate the white flashes when first loading a page, which the author is working on.

Really good but today (Nov. 12 2020) the annonation text for movies at IMDB site doesn't convert into white and still black-on-black.

I've tried them all and this is 100% the best one. good job team.

muito bomm...........
