As explained in bug 327244, checkLoadURI and checkLoadURIStr have been removed from the nsIScriptSecurityManager interface. We need to flag all instances of these function calls and show an error. This is a compatibility error, so the add-on should not be upgraded in this case. Message: The checkLoadURI and checkLoadURIStr functions have been removed. You should use checkLoadURIWithPrincipal instead. See <LINK> for more information.
