Dark Reader might have best dark mode, but it too often slows loading of websites to a crawl, making it unusable. Thankfully there is this addon as a repacement. Dark mode quality of UltimaDark is certainly sufficient and websites load fast with it. So glad I found it. Especially since the rest of dark mode addons seem abandoned. So thank you so very much ThomazPom for this great addon.

Noticeably fast easily the Best Performance for a Dark Mode Add-on, it's definitely experimental and requires difficult development, I'm using Fennec on Android and I'm encountering a bad visual bug if attempting to reusing the search bar on brave if java script isn't disabled. Other then a few websites most other visual bugs are minor and this add-on is very usable even on it current version, of course further development is much appreciated, Thank you ThomazPom!!

I thought it was better than Dark Reader, but after the latest update it's giving errors on some pages like Facebook or Instagram when the page reloads after logging in.

Edit: I edited my review because the extension has good support and attention from the developer.

I love this addon but it would be great if there were more customization options. A few websites that I use do not work completely with the addon turned on. Ofc excluding these websites from loading the addon works but I think that it could be improved so the whole website wouldn't suddenly turn black. <3

I just change my star rating to 5. The latest update really good, it fixes a issue that a lot of sites become dark and unusable✨

Everything is working as expect. But there is a bug in some sites changing all text to unreadable letter.
I think HTML filtering is the cause.

I don't actually turn this on very often because it still needs as ton of work, but no one else is working on what this might eventually achieve. It's open source.

holy shit this is fast and also available on android too. thank you

It works great, but too heavy on my browser :(

Good

Much faster than other dark mode extensions, however it has a tendency to break icons and images.

loading fast than Dark Reader and work fine, good job
but sometime load "discard tabs" will break the web page

Worked!

worked!!!
