Thunderbird 3.0b3 Tabbed Email Viewing

[Robert L Cochran]

It looks like the recent update of Thunderbird to 3.0b3 is using tabs 
for viewing emails much the same way Firefox uses tabbed browsing. The 
tabs seem sticky, so that when I open Firefox, I will see the last 
couple of emails I read. I'm not complaining, but I can say this will 
take some getting used to. I keep closing Thunderbird accidentally, when 
I think I'm closing a tabbed email.
