Greasemonkey against an iframe using @include - does this work? [duplicate]
This question already has answers here : Apply a Greasemonkey/Tampermonkey/userscript to an iframe? (3 answers) I'm wondering if you can have Greasemonkey execute against an iframe only and not it's parent window. The parent window is domain A, the iframe is domain B, and the include in the script would be @include http://domain-B.com/path/ *. I don't need any interaction with the parent. I've tried this a couple of times without success. Is there any cross-domain restriction preventing someone to execute against the iframe? PS: The iframe has JS code that prevents it from loading as the top
