Links in Thunderbird email open new window in Firefox

[Gene Smith]

I don't know if this is a user problem, TB problem or FF problem or FC3. 
I think I have the FF prefs right and no matter what I do when I click a 
link in TB I get a new window in FF when I really want a new tab. Does 
this actually work for anyone? It worked as expected in mozilla and 
mailnew in FC2 but not with FF/TB in 64bit FC3. This is with
FF: 1.0
TB: 20041216

Was using TB .9 with same results.
