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.

Putting a gun to your head for money .. no thanks. There other extensions doing the same thing just as effectively.

Triple-reloads websites and makes them incredibly slow, holy garbage tool, $120K of supporters' money down the drain

It pains me to rate it this low as I do love it, but with the last update it's now slowing down google docs to an almost unusable state. A shame, since it's the only reason I have this addon and until now it was seamlessly functional. Messed with settings but the only thing that fixes it is turning it off entirely. Using a mac.

Yeah this is a complete bait and switch scam. It comes off as a "free extension" but when you download it they straight up are like "give me money or we'll lock the extension and also cause physical damage to your computer with a "memory leak" issue." Most of the "5 star reviews" are obvious AI bot reviews too, so don't let that fool you either. I mean sure the saying its "FOSS" but requiring payment is one thing and yeah you should just say "we require payment" on the ad. Purposely wording things in a way that beats around the bush is scummy, but a lot of these extensions and apps do this and it's expected at this point unfortunately.

Having "memory leak issues" due to faulty programming which causes physical damage to someone's computer, and to also require payment at the same time makes me feel sorry for the unfortunate people that are less computer literate that actually paid these hacks $10 and are wondering why their CPU and Memory are running at max load constantly. Use that $10 or whatever the exchange rate for your country is and go to the local corner-store and get a cheap pair of sunglasses if you need dark mode this badly. It's safer for your computer, phone, and wallet. We're in a memory shortage crisis as is and these jerks are going to cause you to be paying more than $10 for their badly programmed "gimmick" down the line.

this extension causes huge memory leak in FireFox, just imagine Google search page takes about 4Gb, as well as YouTube page loads 4Gb of something filling in RAM.
after removal DarkReader from FireFox - situation with memory leak came back to normal.
do not install this extension if your still want to use FireFox.

Will never use an extension that asks a user to pay money. Sorry.

Your last update screwed every single web site I go to, and that is no exaggeration. Every web site now has some random color, changed every color...doesn't even follow my OS or my Firefox settings. This is unacceptable, completely unacceptable. It's going to take me weeks to reset everything. I'm really tired of bad updates.

Performance was always icky on Firefox, but recently its just horrible, unusable on low end devices and frequently pushes hardware temps up (the way i even noticed it on main powerful pc, its not felt but you could see high cpu use by stats)

Freezes after last update (Allegro.pl for example).
Zawiesza strony (na przykład Allegro.pl).

Freezes, after last update.

Freezes, cpu util. 20% (ryzen 3900x) - after last update.

The latest update causes the browser and even the entire PC to freeze due to very high CPU usage.

I've been using Dark Reader for years, but now it slows down and even hangs my browser. When I use Firefox Settings to set backgrounds to black, I lose highlighting effects. Absence of a working dark mode could cause me to abandon Firefox. :-(

This extension hijacks searches to include their referral tag to steal rep and/or money for themselves. When directly going to www.google.com and running a manual search in the search bar, this addon hijacks the search to include its referral tag, making Google think this app initiated the search. This is similar to how Honey steals money via referral codes. Go to Google, run a search, then disable the addon and do the same thing. Compare the URL bar.

dark reader recently started really slowing down web pages like reddit. a shame because the contrast toggle is really useful

Used this extension for many years and loved it. I had to remove it recently as it was severely slowing down my web pages. sad

Used to be great, but more and more it'll make some sites like run 10-30x slower until they crash your browser tab. (Tested and confirmed it was this extension)
