Gut aber frisst viel zu viel an System Ressourcen und macht alles langsamer. Manchmal laden Webseiten ewig, so dass ich mir lieber Weißlicht ins Gesicht strahlen lasse anstelle wie DFÜ Zeiten zu warten

One of the best add-on for Firefox!!!

My choice for automatic CSS modification which works so well that some websites look much better with Dark Reader than with their default designs.

Has a performance toll on your computer though and occasionally you might encounter issues (I recommend learning the keyboard shortcut to quickly toggle a website), however considering the complexity of automatically transforming stylesheets of all websites it's really a remarkable job done by the Dark Reader contributors.

Works great, on rare occasions, it might act funky and make text dark against a dark background.

there is no options or settings page on the extension management page. all other extensions have settings/options, this one doesn't.
