Great extension !

Would it be possible to introduce a whitelist/blacklist, where you can specify on which sites should the specific rules apply, this would be also better performance wise.

Also, can you add more regex rules/matching in your wiki, for example if we want to emulate above functionality using regex:

Example rule:

- Cancel all .gif file requests to domains example.com, example1.com, example2.com

Is this the correct way to handle it, or is there a better rule/option/function in the extension ?

^http(s?)://(.*)\.example.com|example1.com|example2.com/(.*gif)

Thanks,

Kind regards
