ALMOST.... Perfect. Everything my eyes needed since then. Although, I wish there's an automation button that automatically darkens the website since I don't want to toggle every time I visit a new site. However, it's still an helpful app tho!

so many options, including contast, brightness, and grayscale. By far the best extension of its kind!

As others have said, this works fantastically, but it slows things down so much you can't actually use it :-(

Extremely poor. Veerrry slow. Completely useless. I've never seen such a slow running software. I do not think this developer has the talent for software programming.

Almost perfect dark-mode for almost every website.

tight add on my guy

This Extension provides excellent dark themes on almost all websites. But when I visited sites such as redhat.com/en/blog/..., my CPU usage went all the way to ~90% (a fairly new Intel i5) and RAM (4GB) continued being filled up until the whole system crashed.

Works on almost all sites. Loads well, though sometimes there's a flash of the original site before it loads.
Doesn't work on the firefox site though.
Overall, very useful.

This addon has gotten much better but in the last week or so it stopped working on addons.mozilla.org. I have all the necessary about:config changes made to enable it to work with this site, but it just...doesn't. Was working fine before.

Slows down sites to the point of being unusable. No read the manual section. Counterintuitive settings.

Almost Best Addon Everr!!
