I have tried at least 6 other "dark theme" addons to make every web page appear in "dark-mode", and this one is, by quite far, the best one out there. Has a few minor quirks (that can easily be overlooked) but for the most part, it's excellent. There's only 1 feature I wish it had (maybe it does and I just don't know how to set it up) and that is I wish it could distinguish between different directories on the same domain. For example, if I had a site "www.mydomain.com" in dark mode with this addon, I wish I could set "www.mydomain.com/somedirectory" to not use the addon. It appears this addon can only be toggled on a root domain basis, and not domain/directory. I just don't think you can get that granular with Dark Reader... am I correct? Otherwise, love this addon!

it is an awesome extension for the dark mode theme for firefox.

nice addon

Super awesome extension. A must-have for anyone...

I have tried a few dark modes for firefox and so far this is my best experience. No youtube invert, not making websites that already are dark any weird/buggy, and lets you have parameters.

Some sites have contrast problems, but for the majority of sites, it works really well! Must have extension for sure!

It just doesn't work on some sites like the addons.mozilla.org one

Great add-on for dark mode with many customable settings. It works nearly everywhere. However the best looking mode "dynamic" is quite performance intensive and it does not work everywhere; e.g. Azure DevOps, the left menu and the top part stays unchanged.
