The funny part: doesn't work on this page! :D
And, tho it's not too important to me- all those dark modes listed as options? They don't work at all.
I'd like Bernard, and all coders of extensions like his, to note that some crucial on-screen elements [like the "Rating" field with its 4 stars to click on for these reviews, are hidden when his (and other) dimmers are used.] Maybe it's not worth the work of fixing, but it is worth adding a warning, for confused and frustrated users.
