[tor-project] Future of Tor Messenger

Hi, As some of you may have already noticed, the Instantbird team (the chat client on which Tor Messenger is based) has announced that it will no longer maintain the user interface for Instantbird and instead will work towards improving the existing chat support in Thunderbird: http://blog.queze.net/post/2017/10/18/Thunderbird-is-the-next-version-of-Instantbird So far, we have been maintaining two products: Tor Messenger and TorBirdy, and this change is an opportunity to consolidate those efforts into one application, which we are tentatively calling "Tor Communicator". By doing this, we can continue maintaining Tor Messenger for our users and adding new features to it, and also prototype the "Tor Mail" bundle as has been requested in the past. (This change will only take effect at the next ESR major version bump, in March 2018.) We would still like to stay within the Mozilla ecosystem so that we can continue making use of technologies like Tor Launcher and the secure automatic updater patches from Tor Browser. While we have not done builds for Tor Communicator yet, we expect no restrictions on the technical side as we have released "Tor Mail" bundles in the past. Tor Messenger releases have been based on Thunderbird's ESR schedule as Instantbird releases have been infrequent. This has been possible because Thunderbird and Instantbird share a common source tree in the comm-central repository. There is also the question of the future of Thunderbird itself, summarized in the "A Bright Future" section in the blog post detailing Thunderbird's future: https://blog.mozilla.org/thunderbird/2017/05/thunderbirds-future-home/ By making this switch: - Users will get access to secure chat from Tor Messenger and secure email from TorBirdy, in a single application - Thunderbird has a single-window chat interface which is different from Instantbird (and better) - We can continue supporting Tor Messenger as a chat client for IRC/Jabber/Twitter - Users will get a Tor Mail application which has been requested for a while The idea behind this email is to brainstorm this switch and solicit feedback from the community, so please share your thoughts! -- Sukhbir
