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.

this pretty much does what you'd expect it to - darken all the backgrounds and certain other elements of webpages (that allow it to) :D it works really well for most websites for me! sometimes i have to turn it off on already darkened websites since it may make it harder to see the text and such, but i wouldn't expect this to be perfect. i love it simply for what it does for the majority of websites i visit! highly recommend checking this one out!

Does as advertised... The bad reviews complaining about lack of toolbar button might need to take their computers back to the store
