It modifies structure of web pages rather than just making them dark. Sometimes the web pages aren't usable because of this add-on.

Was really enjoying this extension until recently when it kills itself a few times a day. I have had to "turn it back on" because all my websites are burning my eyes 3-4 times a day now. Never had this problem until last week.

so amazing that I created an account on here just to say "it's amazing"

FANTASTIC! This is exactly what I wanted. Wonderful to be able to change the brightness and contrast. I'm donating

thanks

aún le falta pulir un poco más, pero esta excelente, comparando con otros 4 complementes es el mejor que he encontrado, lo recomiendo muy

Works really well on most sites.

Great addon. Not a single issue so far, all works perfectly. My only suggestion is I'd like to be able to chose default state. So instead having to disable it on the websites I don't want it on, I'd prefer to have it off on default and just enable it on the websites I want it on.
