This extension slow down your browser/crash. In pages who is already "dark mode" it will break the page making is frustrating. Isnt intuitive IMO. But the last straw was the addon changed my dark toolbar to grayish and white (when addon is disabled) and didnt saved my previous toolbar (I clicked to check what the function did). Oh well, to much hassle for now. I can see it having potential to be a great extension but for now I wouldnt recommend it.

Edit: 1 month later after disabling it I still have issues. I wish I never had this installed. I would understand something Ive downloaded outside the official addon page screw with my browser. But for an "official" and recommended extension I cant stay quiet and do nothing.

The best dark theme I've tried so far. It keeps the pages elements. No problems loading pages so far (errors or slow navigation).

This extension will slow your browser down like hell...! At one point I almost switched to chrome thinking it was firefox that was the problem. Firefox would take nearly 10 minutes to start after a few days of installation of this extension. And even after the browser has started it would take decades to load the site. And suddenly every thing started working smoothly as soon as I uninstalled this piece of crap. A piece of garbage is what it is..! This should be removed from the add-on store all together if not improved.

An absolute must have. This extension does an incredible job of automatically converting the entire internet to dark mode, greatly reducing eye strain. Its styling rules are almost perfect, in most cases better than the websites' own custom-built dark themes. The keyboard shortcuts work well to quickly toggle Dark Reader for the occasional site that it doesn't play nicely with.

Looks great, but it causes frequent slowdown and hesitation on web pages. I know this extension is the problem because when I disable it, the issues go away. I prefer the "Dark Background and Light Text" extension.

I am giving only 4 stars although this extension is very usefull and user friendly from my experience for 3 years, i had no problem with it.The reason why i give 4 stars, it drains net, i have a slow network if we use so many tabs they shows like that this extension make tap to close. So no other problems,,, i prefred to my friends also...
