The Mozilla Foundation has announced that a new version of the popular Thunderbird software for Windows, Macintosh, and Linux is in the works. Thunderbird is available free of charge and presently has about 25 million users.
Several new features are planned. Privacy advocates will notice that the next release will include encrypted messages as well as encrypted chat capabilities. The plan is to make encryption in Thunderbird “just work” without expecting users to know how to user or handle certificates, as well as removing technical jargon. They’re also aiming to implement Off-the-record (OTR) messaging for encrypted chat.
