I just discovered that I have Virtual Identity installed in TB - but I 
have never used it. After I installed Add-on Compatibility Reporter 
(which is the extension I was referring to above) for Thunderbird I 
think VI now works - but I haven't tried it because I don't even have it 
configured. However, you use it so perhaps you could see if it does work 
after installing ACR.

Also, there are 2 extensions which appear to do what VI does and they 
are compatible with TB #6. These are: Identity Chooser and Correct
