I use Stylus for Waterfox to fix all the issues with websites. Waterfox is effectively Firefox without getting rid of what made Firefox truly customizable: it's native extensions.
Recently an extension corrupted my profile and I had to semi-rebuild my Waterfox profile. I know all about where the profiles for Firefox/Waterfox are stored though I'm not certain where the customizations per site created via Stylus are stored. Where do I find those customizations so I can port them over to the new/fixed profile?
