2022-12-04 Firefox user 17681028 Throws all kinds of errors for no reason, even with basic elements like #header. It doesn't have any formatting aids either, though I suppose if all you care about is size that's not a dealbreaker.
2022-11-17 Firefox user 12137900 It worked just fine for me. I used it to override the defaults in a website; this extension applies the CSS rules across the domain, and refreshing the page doesn't remove them. Note that extensions aren't allowed to work on any Mozilla domain, so users have to test it on any other website.
