Upgrade to Thunderbird 68
At some point, the only way for us to get Thunderbird security updates will be to upgrade to 68.
When we do this upgrade, we should probably:
- ship Thunderbird straight from Debian (i.e. stop building+uploading our own package)
- apply our remaining account wizard patch (OAuth2) to the relevant files in
- update our doc under
This would address most of what's left of the problem (having to build+upload our own Thunderbird packages regularly) that made us put #6156 on the roadmap this year. I'm saying "most" because until #6156 is done and that OAuth2-related patch is upstreamed, maintaining this delta may have a non-negligible cost.
The beta is scheduled for early June. Draft release notes: https://www-stage.thunderbird.net/en-US/thunderbird/68.0beta/releasenotes/.
