It's good only let down by high cpu usage even to the point it causes firefox to hang. Should do better.

This add-on used to work good but now it crashes my browser anytime I turn it on

In principle, I really like this plugin. The dark mode is super comfortable. But, as others have reported, many websites experience a lot of latency and Firefox suddenly needs a lot of GPU power, even if the plugin is not activated for that website.

Maybe someone can help.. I don't have this little icon to adjust brightness, contrast etc.

The Blue Type is blurry. Please address this NOW. or I will request a refund soon!!!

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.
