It does not work on Android or PC Windows.

Absolutely crazy how well this works and it's faster than Dark Reader

The extension works great and the developer is a cool dude. But on some websites it's just not working well. For example IMDB.com is all garbled up on Firefox on Android, the preview videos fail to load and some images just won't open. Please be kind and fix it.

Thank you so much ThomazPom, you're doing God's work!

Dark mode doesn't work after version 1.6.22! Fix pls!

Update: It works after Add-On reinstall!

After the recent updates the addon became truly amazing. Especially for OLED screen users.

I've used a few different dark mode extensions over the years, but UltimaDark is FAST! Not only is it fast, but it handles websites with progressively loading content far better than even the fabled Dark Reader.

Correcting my last rating. The extension is broke on Ironfox, Iceraven, and Waterfox. Enabling will temporarily keep it running on most sites, but exiting the app will break it.

*Update - the extension might be going through too many growth spurts atm.. it's been hit or miss for the past few weeks. Going back to the heavier/slower Darkreader for the time being.

I'm really glad to see this excellent extension getting an update! For me, one of the biggest hurdles in moving away from Chrome-based browsers has been finding a good dark mode solution. This extension has great potential to remove that hurdle, which is why it's the one I care about the most. The updated modern UI looks fantastic, and I hope more people will discover how great this extension is.

Just discovered this extension and really surprised at how its even faster than chromium in rendering dark mode! However, I see there hasn't been any new updates this year. Really hope you don't abandon this awesome project!

UD's way more lightweight than the bigger extensions; thank you so much Thomaz!

One issue I've been running into is Twitch streams being covered by the extension. I've tried changing the "precision" value (tried 1, tried 10) and it hasn't seemed to make a difference. Hope you can provide some help with that, but great work otherwise!!

Edit: I see that this issue's been brought up on github back in February. Hopefully progress on that's still going well!

Only using for a few days now, but the performance difference compared to the absurd Night Reader is instantly noticable. It's certainly not perfect yet but after changing to this it's difficult to go back.

Great addon! Would be awesome if you could apply dark mode per window, so that I can keep the window on the main monitor with light theme, and apply dark mode for websites only on a secondary monitor.

Just the fact that you have to reload if you change a setting makes this worthless.

Oh goodness, finally, a dark mode extension that works well enough and does not destroy my device. Thank you. We can deal with the bugs, please keep developing <3 (and yes its seriously fast)

It hasn't actually worked yet. It doesn't change anything about the pages on this website, for example, or YouTube. Something may be blocking it, but I enabled permissions when asked by Firefox. I don't think it's uBlock, because it behaves the same way when that's disabled. Please advise! Or help

super fast

Would love to be able to blacklist sites to not run this (Gmail behaves funky when this is enabled, I'm sure there are more sites that I'll run into the future)

Other than that it works great.
