has been getting extremely laggy recently, even in filter / filter+ mode. Static mode seems fluid but it's a subpar look for websites.

世界上最牛逼的深色模式插件。

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).

It saves my eyes from occational flashbang while surfing the web at night.

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.

it works now

last update broke something - it slows down the browser and firefox asks if i want to stop this extension

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. :-(

One of the best extensions I've installed. Simple, effective, and doesn't bloat the browser at all.

Efficiently renders webpages as dark by altering elements directly (by default). Very effective at eliminating bright backgrounds no matter the source. Interface is a bit clunky with four subpages to sift through, and verbiage a bit confusing. Can rarely unintentionally hide elements from sight, so double-check a page with it disabled in case anything is missing.
