The Thunderbird 78.x release is a stable release but is not yet being pushed out to existing portable or local users by or Mozilla. It will not work with existing Enigmail/GPG setups or many existing extensions. As such, we're releasing it on our Test channel for now for users to test out and report issues alongside their standard Thunderbird Portable installs. This release now supports 32-bit and 64-bit dual mode and modern extension portablization.

Sometimes, the impossible can become possible, if you're awesome!
