I've been using Thunderbird on my Mac for over a year. I came into work today and there is a question mark on the icon that is in the doc and it will not open. Help!

tried restarting your mac? I ask because I find those with MACS for some reason do not try that when their device has issues.

Otherwise try a reinstall from getthunderbird.com and see if that clears it.
