Mozilla has released Thunderbird 3.1.4, the latest version of its open-source email client. The 3.1 release – which came out earlier in September – made it easier to switch to Thunderbird, whether from earlier versions of the software or from other email clients, thanks to its new Migration Assistant. The new version also introduced tabbed email browsing, mirroring the popular Web browsing feature. Other new niceties include one-click Address Book editing, an attachment reminder (which warns you if you try to send an attachment-free email when your message implies that you planned to attach one), and a Quick Filter search bar for finding messages faster. The 3.1.4 maintenance
update corrects a few bugs related to the program’s stability and interface. (Free, 20.5 MB)
My version of Thunderbird is already at 3.1.4 for OS X.
The new Version 3.1.4 is running on my different PCs. The main feature it is TOO SLOW. It always waits for any action seconds and sometime it can not save. If it downloads from internet any other action is blocked.
