Used the Addon version before this and I wouldn't run TB without it.
Next time I'm forced to upgrade Tbird, I'll be looking for a different email program.
Mail toolbar buttons won't appear though (on Win7, I tested TB 60-60.9.1 32/64bit). Ended up using CompactHeader to move the buttons to the side... I think the icons are too large for the tool bar height so they don't appear.
(View -> Toolbars -> Customize) as explained in the description does not do anything.
