Mozilla has announced it’s ceasing development on Thunderbird; one more version will be released, and it’ll be security updates from then on. “Most Thunderbird users seem happy with the basic email feature set. In parallel, we have seen the rising popularity of Web-based forms of communications representing email alternatives to a desktop solution. Given this, focusing on stability for Thunderbird and driving innovation through other offerings seems a natural choice.” Makes sense – I mean, there’s only so much you can do with something that needs to send and receive mail, and I can’t imagine Thunderbird having a lot of users. Strange, almost Microsoftian obtuse announcement, by the way.
