↳ In-reply-to » I was today years old when I learned that Firefox supports custom per-domain CSS. Is this new? I thought I had tried a while ago and it only worked globally. 🤔

@sorenpeter@darch.dk In your profile folder (somewhere under ~/.mozilla on Linux), there’s a chrome folder. You can put a file called userContent.css in there.

This also needs the setting toolkit.legacyUserProfileCustomizations.stylesheets to be true.

(I hope they never remove this, it’s super helpful.)
