Works for most sites tolerably, however it breaks the kindle cloud reader (read.amazon.com) regardless of whether it's toggled on or off, and regardless of whether you put it in the whitelist or not.

Technically works, sometimes. But very poorly. I've seen other extensions do a much better job. This one basically has to have a custom stylesheet for each individual website to work properly, otherwise buttons are disappearing, menu items are vanishing, backgrounds are becoming transparent, it's not just changing the way websites look it's changing and breaking their functionality too.

Amazing! It offers a variety of dark themes, but even the default one "Dark mode #1 (simple dark)" is so good that I didn't really try the others. There is thought put to the color palette, it's not just pitch black but a lighter dark much more pleasing to the eye. Furthermore, the turn-off button is conveniently/easily accessible as there are some unavoidable cases when sites will be broken or incorrectly displayed.

However, I do have some concerns about privacy: why does it need permission to all our website data? Does it have display-customizations for certain sites so it needs to check at runtime which website is loaded?
If yes, ironically, the addons.mozilla.org is not affected by the dark mode :P

It does what it says, but unfortunately it was causing all sorts of breakage on sites I use. Tons of SecurityError: The operation is insecure. and other issues showing in the console.

Why does this web extension need to access all our website data?

Currently breaks Kindle Cloud Reader, even when read.amazon.com is whitelisted. #DealBreaker

Works as it says in the description

great...need to add option to activate from context menu also

this is definitely one of those add ons I've been looking for my whole life...I'm a biotechnologist and read a lot on web...keep up dating it make it unique....thank u Bernard...

Simply the best dark theme provider - tried many others for individual sites but this one works for all sites and works great.

Edit: Some issues; it inverts gifs and other things on twitter so you're better off disabling it for twitter and using twitter's native dark theme

One or two other sites don't get along but you can turn it off for a second on those.

Would be nice to have a list of sites it's "on" for and "off" for.

It's really work!

It is not completely perfect on every website but still it does exactly what I need

Looks great, and also has clean and nice icons.

Seems to mess up some embedded videos, though (specifically Reddit and Vimeo).

Amazing! easy to use !!
and the color theme is so comfortable!!!
