SP 52416: Signed Script access is currently enabled in Firefox

Symptom: A Signed Script can request expanded privileges that may give it access to restricted information on your computer. Unfortunately, there are no visual signs of this type of activity when it occurs.
Resolution: This change will modify the Firefox settings to disable granting Signed Script access. By default, JavaScript is not allowed to read or set your clipboard data for security and privacy reasons. This is because websites scripts can erase and replace what you currently have in your clipboard (data loss issue) and they can read whatever you have in your clipboard (security and privacy issue); as such, you should grant access with caution.
Additional Information: For this change to take effect, you must twice consecutively start and exit Firefox.
