Why don't you show full version of the protocol? Only SSL or TLS.Can you show:SSL 3.0TLS 1.0TLS 1.1TLS 1.2

Update.
>Because that information is not yet exposed by Firefox.
Thanks for answer. I thought so.

This review is for a previous version of the add-on (3.7.0.1-signed). 

Because that information is not yet exposed by Firefox.

Also, the PROTOCOL option is currently erroneous, and has been removed in 3.7.1. Expect it to return (with version) once the correct data is available.
