while I enjoy dark reader, it makes websites look a lot better, but dark reader slows Firefox on Android to a crawl, I just cannot take it, and after reading an Reddit post where users were complaining about the sluggishness of Firefox on Android, a user mentioned dark reader being the culprit, so I disabled dark reader.
Problem solved, sorry, not sorry

It's nice but slows stuff down considerably.

Applies dark theme on websites that already darkmode (Youtube) and messes up the UI

Lags firefox on android

dark view works well, but high battery utilization on Firefox Mobile for Android... uninstalling

Constantly having false positives or just not running at all, it's really annoying having to go in every time and disable. Unfortunately out of all the other addons that provide dark mode, this one is the most functional.

Does what it says, but horrible performance noticable on weaker devices.

Lent.

Great Add-on, works perfectly for pretty much every site I use, install-n-forget kidna thing.

The only reason I'm not giving it a 5 Stars is cause it breaks minecraft.net, can't access that site with this plug-in installed

Dark Reader used to work so well but lately it's been breaking on multiple websites. Twitch is overlaid with a gray box and text is often set to the same color as the background. Additionally I've had issues with high CPU usage on certain websites. FF 124.0.1 on Linux.

It seemed very good at first. Loved the sepia effect on several sites. Then, it broke down on several sites - I had to turn it off then on in order to read some texts. Not to mention it slowed down the pages.

It works well until a week ago. Several webpage looks broken when dark reader activate. Currently using on mobile firefox

In terms of dark effect, this extension is the best, but in terms of performance, it is worse. It will significantly increase CPU usage and slow down the web page.

从效果上来说这个插件在同类中表现最好，但会大幅增加CPU使用率，拖慢网页速度。

Алгоритмы классные, но сильно грузит процессор.

In many case better visuals than vanilla webpage, but it does not allow for whitelisting webpages

This works well on most sites, but for sites like Amazon, it blacks out the majority of product images so you end up not being able to tell what you are looking at.

Outstanding visuals in general, but it is worsening the loading times of my Gmail.
