Very good but it doesn't detect if I have dark mode in onedrive website

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.

Un must, mes yeux vous remercie, tant de confort supplémentaire sur certains sites à fond blanc

I installed this add-on because it was a "recommended" extension. I've been using this DR for several months. Today, strangely, it stopped working. I closed and restarted Firefox and DR was gone. It simply disappeared from my list of installed add-ons. Why would it do this?
