The extension does its job well, but with performance impacts.

Really good extension

If it's possible, please exclude the site's video player interface from getting darkened as well (it's hard to see the video scrubber)

Slows performance signifikant and makes some content invisible

Very reliable and easy to use. A lot of features and best all of is that it doesn't collect usage data. I really like the fact that I can set the toggle for individual and specific websites. Well thought-out. Happily donated to this project*
