Option to start program with no mail tabs open

[JohnNozum]

     Probably a few years ago, I suggested about having the option to start Thunderbird with no mail tabs open, much like how Thunderbird used to be years ago before adding tabbed email.  Now, it always starts in the same state that it was closed, even if you have several email tabs open.  Right now, it is the same as Firefox's option "Open previous windows and tabs"----but CAN'T be changed that I know of in Thunderbird.

I have a issue with thunderbird trying to start (unsuccessful) and I believe it is because of a tab which is openning. Please can we have a safety option so that we can start with NO open tabs?
