Verisign/Symantec Certificates In Thunderbird

[Sajan Parikh]

Can someone do me a quick favor?  Preferably someone who has not 
installed any keys manually into Thunderbird since installing Ubuntu 13.10.

Go to Preferences > Advanced > View Certificates

Can someone confirm whether or not the following chain exists in 
Thunderbird by default?

-> Verisign Class 1 Public Primary Certification Authority - G3
--> Symantec Class 1 Individual Subscriber CA - G4

I can't remember if I had to install these myself, or if they were there 
by default.  Want to make sure before we switch.

Thanks.
