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.

feedback: kindly see if darkreader can have in future text selection background color editing

rate: a must have daily browsing tool for dark mode users

The best dark mode add-on there is and nothing else comes close, visually it's brilliant! it dynamically and intelligently changes any page to look great depending on the different sites. I haven't seen one site that looks bad with it. The only problem is the performance hit on certain sites where it causes some slow downs, But it's so good that I don't really mind it that much.

Àss vezes deixa o Firefox lento, ou trava. O próprio Firefox avisa para parar a extensão.

It's mostly really good but on the occasional site, like Aliexpress, I need to disable it and then enable it for it to display the page correctly. I don't understand it as it is still using the same filter when I cycle it but for some reason it has to be done to a few sites to display properly. Other than that this is a must have as while backgrounds are eyeball destroyers.
