Occasionally have to turn it off to use or find some features on some sites but overall a real game changer and I rarely turn it off

This extension breaks usability on more sites than it helps with. Form elements like checkboxes will become unreadable, entire sections of the site that you'd normally see will not be visible, etc.

Great Add-on, ability to disable it quickly with a macro by default is smart!

I installed it, hoping it would make the addons.mozilla.org site dark so I can read without having to squint at the screen that is too bright, but it won't put the site into a dark mode. Can this be fixed somehow?

Super

It saved my eyes.

now a paid app to get all the features. Nope lots of alternatives.

Works brilliantly. Easy to use.

Makes a few sites unreadable, and some have ugly colour schemes, but I can't really blame them. Besides, you can just turn it off in that case.

Great extension. Flips colors naturally while keeping all items as visible as they are in the site's original (non-dark) layout. Very simple to use and highly customizable: You can easily fine tune the darkness intensity. For instance, if you prefer a dark grey theme over a completely black one, it can be easily adjusted. Highly recommended!

The FF version works better than I had expected. It's darkifying many of my favorite websites in manner that looks like the site had its own dark mode. So easy to switch on and off too.
