I used to have an extension per each domain then I've decided to publish regurlator https://chromewebstore.google.com/detail/regurlator/jfgfmidm... ... this case would be like `^https:\/\/(?:x|twitter)\.com\/(.+)?$` `https://xcancel.com/$1` so you have a single extension with as many rules as you like and you can download/share/restore rules with ease (it's just a JSON file).
