There are two things you can do if you find yourself in this state:
Close the Firefox browser.
In a folder below the Mozilla/Profiles folder, located in your account's Application Data folder, find your browser profile's prefs.js file and delete the following two lines:user_pref(“capability.principal.codebase.pX.denied”, “UniversalXPConnect”);user_pref("capability.principal.codebase.pX.id”, “<iManager URL Root>”);where“<iManager URL Root>” is the root of the URL of the version of iManager you are using; and “X” in the “...pX...” of the two settings match
Restart the browser.
