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.

Preying on vulnerable people for their money is very bad, why can't you just help us like you used to from the goodness of your heart? money is the root of all evil, i thought you were a good person, i guess i was wrong, you gave in to corruption. Thanks for letting us people with conditions and no money suffer more now than we do already, very nice of you!!

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.

Very useful.

Used to be a great extension, but over the last year or so it's gotten worse to use. There is 0 reason a PC with a 16 core / 32 thread cpu, 32gb ram, and a 2070 Super FE should have frequent tab crashes and closures over a DARK MODE EXTENSION. Optimize your code, goodness. I can't even open facebook anymore with the extension on, it's gotten that bad.
