Mozilla Firefox is vulnerable to certificate validation bypass. An attacker could first obtain a valid signature for a fraudulent addon, which can be done without review, then hijack the call between the user and AMO to replace the response from /update/VersionCheck.php with the IDs of the fraudulent addon resulting in man-in-the middle attacks.
