As I work on a personal HTML + JS app, the ability to access the content of iframes or opened windows with Javascript would be extremely beneficial in boosting my productivity.
I am curious if there is a way to bypass the cross domain restrictions set by Firefox 7.0 so that I can edit the contents displayed within an iframe?
It seems like I encountered a similar issue in Firefox a while back. Here's a possible solution to try:
You can find a file called prefs.js in your user profile directory. On my computer, it's located here:
C:\Users\simon\AppData\Roaming\Mozilla\Firefox\Profiles\aoagj1zo.default
Inside this file, there are several lines that look like this:
user_pref("accessibility.typeaheadfind.flashBar", 0);
user_pref("app.update.lastUpdateTime.addon-background-update-timer", 1317146699);
Consider adding the following line to the file:
user_pref("capability.policy.default.XMLHttpRequest.open", "allAccess");
After making this change, be sure to close Firefox, edit the file as needed, and then reopen Firefox.
