In Brave I can see a preview of the page by hovering over the tab. Is something like this possible in firefox? Add-on or from settings?

    Did you toggle on toolkit.legacyUserProfileCustomizations.stylesheets? Firefox stopped parsing userChrome.css by default since several years ago.

        It doesn’t work for me, but I have nonstandard setup. It appears that as long as the black box shows up that means the css is loaded.

        Incompatible with built-in browser themes “System theme – auto” and “Firefox Alpenglow”

        Are you using “System theme – auto/dark” by any chance?
