While it works beautifully, it has a super high impact on the performance of a browser, whether is it active on the website or not :-/

love this thank you for 12 years.

its good, it helps me read at night

I stand corrected for me previous review: one website that was giving me the biggest of troubles was attempting to do its own dark-mode, saw this app working: and both doubled down and looped in itself, creating weird artifacts that (Well, I think I was seeing the matrix..).
Whitelisted the site, reset the website to use its own darkmode, and everything works great again.

One point I bring back from my previous 3-star review: "this extension is my go-to plugin for every system I use Firefox on". Really, I value a good dark filter over ad-blockers.

Absolutely fantastic addon that has worked on every single site I've thrown at it. The only downside is a bit higher resource usage than I'd like but it's bearable on my more modern systems. Mobile and lower end devices? Dark Reader makes the browser chug.
