On pages it looks like this where you add css or js.And in the config part of the extension you can see all sites. and also a basic cut and paste printout of all applied script. (there is no import/export feature yet) To remove a site from the list just go to it and clean out both boxes and hit apply. Or uninstall the extension.
About this extension
I could not find any newer injector so I made this with AI. The latest version adds ability to overview all sites where you have injections and activate/deactivate them. So you eg. can't lock yourself out from a site... like I did 🤦🏻‍♂️😂.
