Hi,

are any details available about the SSL Proxy product or device vendor?

(Why did mozilla (https://bugzilla.mozilla.org/show_bug.cgi?id=946351)
remove the information
about the device vendor from the bugtracker? I'm just curious and
forwarding questions I got from reporters).

The comments also mention "..although it is odd that the certificate was
observed outside of France". Are any more details available?

At which location was the SSL Proxy used and which Internet traffic was
affected?

thanks & regards,

ralf
