Relative to:
Basically, I have a page-mod which should append an iframe element to the on going Web page. That iframe should load a Web application from the extension’s data folder. Then, that application might communicate with the page-mod (or the add-ons scripts) through the standard postMessage
API.
It’s pretty much what I’ve done with a Chromium implementation of that extension.
Unfortunately, doing so with Firefox doesn’t work as expected:
Security Error: Content at http://mozilla.org may not load or link to resource://<extension-id>/data/main.html.
Some work-arounds have been given on bugzilla, but it’s been a little while and I’m wondering if any one had find out a proper way to do so?
