I have a web-page where I have injected Content Script (webextentions). JQuerry adds stylesheet here. How can I do it to add the same stylesheet which is in the web-page to its iframe document? I think it is not possible to access the iframe document by the Content Script, is?
This was asked in 2010, today in 2015, this
would not work in any newer browser, unless you are developing to
google.com. Because of cross origin policy, you cannot access the
content of the iframe, if it points to a page on a different domain than
the one your original document is loaded from.
