问题
I want to "proxy" web pages through a chrome-extension:// page (using an full-frame iframe), so that they show up as an extension page, instead of a webpage. I still want to apply content scripts to them, however, and have not had any success doing this. Is there a way to allow the chrome-extension page to access the contents of the iframe because it's "privileged" and should be allowed to get around XSS limitations?
Whenever I try to executeScript( { code : blah , allFrames: true }) I get an error about XSS about the chrome-extenion page, not the http page inside it...
Ideas?
