Option to NOT open up email tabs on startup
I think it would be nice to have a startup open to NOT open up email tabs that may have been open from a previous session. Newer versions of Thunderbird (probably the last 5 years or so) AUTOMATICALLY open up ALL emails that were open from a previous session. To me, this is a lot of clutter. I think this issue started tabbed email capability in Thunderbird. I would like the option to start out with a "clean slate" (no emails open) upon startup. Attached is a screenshot of how I would like to see the option of Thunderbird starting up as.

There is an add-on to set the startup folder, no matter the folder that was open at closing, but the only way I know to close all open tabs before closing TB is to right-click the main window tab, Close Other Tabs.
The latter portion of your response was the most relevant:
'but the only way I know to close all open tabs before closing TB is to right-click the main window tab, Close Other Tabs.'
I tested this, and it works. I know that older versions of Thunderbird, which did not have tabbed capability, didn't have this issue. Some web browsers, including Mozilla Firefox DO have this option to start where you left off at (i.e. multiple tabs open / not on home page(s)), or to start with a blank page or a homepage of your choice. If you compare the recent versions of Thunderbird to Firefox, it'd be like the only option is to pick up where you left off at. (clutter and all).
With browsers, there's less need to restore the open tabs, since the History keeps track, but in TB there's no equivalent, so restoring the tabs might be essential for some users.
