Thunderbird 3, Almost Ready, Gets Bug Fix

Mozilla is preparing to launch Thunderbird 3 soon. The current production version is Thunderbird 3 Release Candidate 2. They just released a critical bug fix (Bug 494014) that affected all versions of Candidate 2--Windows, Mac, and Linux.

This critical bug caused the program to stall the shutdown operation, consume too much memory, and close all IMAP connections ("shutdown hang, high cpu, no open imap connections per netstat").

The release of Thunderbird 3 is already one year late from it's original launch date. It has also missed it's current, planned, launch date of November 2009.
