make sure thunderbird is closed down first.
then copy ~/.thunderbird/profiles.ini from the old machine to the new one. (this should've happened when you copied ~/.thunderbird)
this is the file that points to your profile.
you can look at it, it's just text.
if you really need to, you can edit it.

Well. Result happiness with Firefox at least. With regard to Thunderbird, things are a touch more complicated. This may be my fault of course. How do I get it to recognise my old profile as the default? I now have three. It's not good.
