Mozilla fixes memory-hogging bug in Thunderbird 3

Email client almost ready for blast-off

Security for virtualized datacentres

Mozilla has fixed a serious instability in an almost-ready version of its Thunderbird email client, as well as tackling a variety of lesser stability flaws and adding some enhancements.

Thunderbird 3 Release Candidate 2, released Tuesday a week after the first almost-baked version, fixes flaws that turned the previous test version of the email client into a memory hog and resolved glitches that meant the application periodically failed to shut down properly.

Performance improvements that debut with the release include improved IMAP Folder Synchronization. The latest test version of Thunderbird will download IMAP messages automatically in the background, as explained in Mozilla's release notes here.

Thunderbird 3 Release Candidate 2 includes boasts better search, tabbed email, and message archiving improvements compared to the current version of the software, Thunderbird 2.

The long-delayed final version of Thunderbird 3 is expected early next year. Mozilla is yet to name a final release date. ®
