I've used this for a while and put up with one very annoying problem: it makes no exceptions for its styling and ends up inverting embedded videos (and similar types of page elements). If this was fixed I'd probably continue using it but I can't tolerate it anymore so I'm sticking to Dark Reader.

Excellent but it would be great to have a brightness adjustment. Besides as others reported it doesn't work in some sites. i.e. IMDB

Life saver for a visually impaired who have huge "bloom" auras around bright areas.

It could be a coincidence, but most of the sites I frequent had defects with this extension, ranging from annoyances to no-nos like changing the background of QR codes to dark, making them unreadable.

Some say that it makes pages look bad. I say that i can now see and read them from my bed 2.5 meters away. Darker theme override makes me sleep better. No perfomance issues found.

Does as it says, instantly. Thank you so much
