Looks like it makes Firefox to heat up my Mac (?).
Firefox 122.01 on MacOs 11.7.10 (BigSur).
As soon as I deactivate it, the temp goes down to normal.

May cause increase in webpage loading time, try disabling this extension if your browser keeps getting "The connection has timed out" error

Its good at changing colours but it causes a lot of lag. Personally, I would look for something else

In the last version there's issue with gitea https://i.imgur.com/oxGmqT7.png

I think there's same number of these warnings as activities @ issue .. it's annoying.

Previous versions were best extension so far.

In the last few months Dark Reader has become unreliable. It won't sense the system mode and will remain in dark mode. Toggling it on/off or automation doesn't do anything, only deleting and re-installing. It used to be fine so this is very disappointing.

Works ok but not with scanning QR-code. Therefor you got only 3 stars. I got the QR-code in the color GREEN. My bank-app did not recognize the QR-code. Maybe an option to change your code when there is an QR-code to be scanned.

The functionality is great, but unfortunately it seems to slows down my browser, freeze Firefox & prevent it from shutting down properly, forcing me to restart my computer multiple times a day.

it... works sometimes, but the speed penalty is huge!

Frustrated I can't work out how to blacklist/ whitelist sites, use sepia, or adjust any parameters at all!

Doesn't work well on Amazon.ca

It works really well for most things, but if a website has a Disqus-style comment section it won't automatically turn it dark and I have to turn dark mode off and on for it to work. I have this problem on SBNation sites and on Angrymetalguy.com

Hi the latest update makes videos Inverted to negative. Please update, Thanks

this hinder scrolling on many website, ex: chatgpt

Only works on some websites (btw, most don't), but does its job.

I have been using this super-useful extension for over a year now. It mostly does its job perfectly, except that the automation feature (that enables/disables the dark mode as per predefined settings) has been broken for about 6 months now, without any action from the developer. So giving it a 3 star rating.

Worked great previously, lately has issues with REALLY bad stuttering when scrolling through some web pages, to the point of unusability with the addon enabled.

On Firefox for Android

Slows down the Android app too much

I found it resources consuming extension on my old Macbook though works as expected.
