featurewise it's a good add-on but it's slowing down the surfing so much i had to deactivate it.

3 étoiles noires serait plus juste

ralenti la navigation
impossible de basculer jour/nuit ( c'est pas prévu)
impossible à désactiver
impossible de supprimer

Very very very very slow !!! I uninstall !!!

Extremely poor. Veerrry slow. Completely useless. I've never seen such a slow running software. I do not think this developer has the talent for software programming.

removed this add-on because I started getting Fake iPhone X for a $1 scam pop-ups in the Firefox browser.

works but too slow, 10 seconds to show a web page?!?!

Let me get this out of the way: It's very well-designed. It does exactly what it says, and it does it in an intelligent way. It actually looks like an official dark mode on every site. The only problem is I can't use it effectively because it murders your CPU and nothing will load. And it's not like I'm on a Pentium 4 that can barely handle Firefox itself, I'm on a $200 hexa-core from 2 years ago running at 3.9 Ghz.

In short, it's well-done, but it's so poorly optimized it's virtually unusable. I would gladly go back to it if I could actually use it.

nice mode but sometime memory leak over 6gb of ram especially when u go to EA website

works on some sites, but made gmail unusable and some sites stopped loading.

few days my internet became so slow.
I couldn't understand what make my browsing so slow... until I have disabled the Dark Reader :(
really sad cause it was great idea

Slows webpages down way too much!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Nicht so gut - schwarz bleibt schwarz, man kann teilweise nicht alles (Bilder, Texte,...) erkennen

Makes loading of certain sites load EXTREMELY slow, such as reddit.com, when enabled on such sites.

The performance is extremely poor. The browser slows down of a great deal.

It hangs hard whenever I toggle it. It make other apps running in background crash too including Firefox.

Slows down Firefox so badly. Even slows down my TST set up, which is fine with other darkify extensions. The features and capabilities are amazing, but this resource hog made using firefox unbearable in some situations, so I have had to remove it in favor of a more simple extension that still gets the main job done without slowing down my browser.

После установки расширения, ни сайты почти не грузятся, ни сам браузер. Даже в настройки с трудом входит, чтобы удалить расширение.
