I like the addon very much, but the webpages are slowed down by a factor 2 or 3! So no thanks.. It's just too slow.

The functionality is great, but unfortunately it seems to slows down my browser, freeze Firefox & prevent it from shutting down properly, forcing me to restart my computer multiple times a day.

Simply the best one and the easest to set. For those who don't see the 'Dark Reader' icon in the tool bar, at least learn how to display the icon of a plugin before criticizing

Every time there is a firefox update I have to remove dark reader and install it all over again on my several firefox installs. Very annoying.

it... works sometimes, but the speed penalty is huge!

the best

Finally, saved!

Not great. Just inverting colors which makes images appear inverted as well. Was hoping this was a true dark mode.
