★☆☆☆☆ ach44 · 12 Oct 2026 · v4.9.133not optimize in firefox

★☆☆☆☆ doclucas · 12 Oct 2026 · v4.9.133Works, but terrible performance issues on Firefox. Much more optimized on Chrome. Come on guys! In the age of AI - you can do a lot better, quicker, before someone else will just take it, fix it and rebrand it!

★★★★★ Lil tech nerd · 3 Oct 2026 · v4.9.133More than just and extension Protects you from flashbangs from sites Although it doesn't work on some sites

★★★☆☆ Sieve · 2 Oct 2026 · v4.9.133Was amazing for a while but currently has way too many performance issues that even extends to sites where it's not even on

★★☆☆☆ Daineic · 1 Oct 2026 · v4.9.133I've used Dark Reader for YEARS but I'm finally throwing in the towel. At least on Firefox, this extension will lag your browser to death. I spent a whole week trying to trial and error what extensions were causing such huge memory usage issues and constantly causing sites to lag. I figured it was something like ublock, canvas blocker, or chrome mask. Nope. Everything lead back to Dark Reader. This extension has helped with my eye-strain issues so much. I seriously hate to get rid of it but I can no longer look over the performance issues. Please, figure out a way to make this extension light

er or at least a stripped back version. I would love to come back and write a nicer review. For now, I will be using Stylus and simply grabbing user dark themes where I can. -
★★★★★ intelfx · 28 Sep 2026 · v4.9.133Rating 5 stars because this feature is invaluable, and I've been happy to donate to the extension's development. This extension made giant strides since a few years ago; I almost don't need to disable it to unbreak sites. The performance could have been better, though.

★★★☆☆ Milan Regec · 23 Sep 2026 · v4.9.131While it works beautifully, it has a super high impact on the performance of a browser, whether is it active on the website or not :-/
