"BEFORE YOU PUSH AN UPDATE, SEE WHAT VERSION OF OSX!"
None because it won't open in OSX 10.4.11
Thunderbird message said there's an update available. Presuming they know what they're doing, I took it. Now Thunderbird won't open because I'm on OSX 10.4.11. Come one guys even Microsoft checks the O/S version before they do an install / update!
Do NOT download this if you're on OSX 10.4.11 or earlier! If you do, go back to their site and choose Other Languages, find English US, and re-install 3.1.14. Geez!
