});

console.log("Addon loaded.");

Question

Using the addon-sdk from github.com/mozilla/addon-sdk with this patch applied: https://bugzilla.mozilla.org/attachment.cgi?id=555753&action=edit 

As you can see in the output, the location does seem to change but when I hit facebook.com and the output shows that I should be on google.com, I still see facebook.com. Is it possible to change the location of a page from within the page-mod's content script?

I would also like to point out that window.location.host returns undefined. I thought it would make sense that window.location in the context of a content script should return a standard Location object as described by the MDN docs: https://developer.mozilla.org/En/Window.location#Location_object

I'm guessing the workaround is to send messages to the add-on code and use the tabs API but I would rather avoid that to keep my extension code as much similar to other browser extensions as possible.
