I've been using it for a while but there are always some issues.

Right now, on FF 90.0.2, it refuses to disable on certain sites (like Unreal Store).

The "Synchronize Site Fixes" and "Enable Settings Sync" options are completely broken. Every time I turn them on, they either turn off or remain on. One thing they DEFINITELY do, is to disable all my custom settings for sites, EVERY SINGLE TIME.

I understand "synchronize" option might be importing custom settings, but why would you even make such an option that wipes out all custom user settings without a dialog box confirming it?

OH you want to remove a specific site from a list of sites in the add-on? Well, I hope you like scrolling through a tiny list of sites, and thousands of domain names since this add-on never heard of a "quick search" option.


This is terrible UI/UX issue as well as bugs that haven't been fixed for ages.

The only option to preserve custom changes is to routinely manually exporting site lists and importing them every time you discover another broken site.

This addons working properly in any site.

Muito massa, funciona bem com a maioria dos sites e eliminou a necessidade de outros dois plugins que eu possuia!

Combine this with "automaticDark", and get a full-fledged light/dark switching experience!

Web Pages load slower with this extension even on my high end gaming laptop, and this is after the data has already been received from the internet for the webpage but the extension adds time applying dark theme to websites. Also extension consumes enough system resources to kick in my laptop fan when alternatives like "Dark background and light text" doesn't.

I really wanted to like this addon. It does the best dark mode and everything works good, most of the times. However, when my laptop is under load, this addon delivers the final blow. Firefox becomes soooo slow!
I highly suggest it if you are a casual user, but if you push you device to work hard you should avoid this. I am sorry. 3 stars.

I love it!

It works perfectly for nearly all sites. Would love the ability to easily specify custom colours for elements on a specific page though.
