UltimaDark - The Fastest Dark Mode Extension by ThomazPom
Review by Cyberdyne
Rated 4 out of 5
by Cyberdyne, a year agoOverall, UltimaDark has replaced the venerable Dark Reader extension for myself. Mostly, down it's speed, and other built in settings to speed it up further. Firefox already isn't the most speedy browser on Android, so anything to keep speed up is a good thing to consider.
That said, it's not all roses. I've had websites not properly set text to a lighter color to keep it legible. It's rather rare, but not so rare — you'll eventually encounter it. It's easy enough to add per site exceptions, but an easy way to set per site color fixes would be a good addition. It is obvious when you should blame the extension, so I haven't been left scratching my head as to why I can't read something at least.
A bug that's easy to reproduce is. Keep tabs alive between Firefox sessions, open a website you need UltimaDark for, close Firefox, then when you reopen Firefox that website will not have UltimaDark applied at all until it's refreshed.
These are minor complaints though, and it's at least worth trying and probably replacing your current dark mode website extension with this.

Developer response
posted a year agoThank you for the detailed and well-balanced review — I really appreciate the time you took to explain both what works well and what doesn’t. A 4-star review with concrete feedback is genuinely helpful.
Regarding text contrast issues: I personally haven’t encountered many cases, but that’s clearly influenced by the set of sites I visit. Other users have reported similar situations, so it’s a valid point. Per-site color adjustments have already been requested in a GitHub issue; it’s something I’m looking at, though it’s non-trivial to implement cleanly without adding complexity or performance cost.
The Firefox session restore behavior you describe is also useful to know. If you haven’t already, feel free to open a GitHub issue with a few details — that’s exactly the kind of reproducible case that can be debugged and fixed.
UltimaDark is actively maintained, and feedback like this helps steer improvements in a practical direction. You’re very welcome to continue the discussion on GitHub.
