Description

Thunderbird 78 should be released in northern hemisphere summer 2020; Thunderbird 68 should become EOL in fall 2020, which will be our deadline for upgrading to v78.

The two Thunderbird patches we created to replace TorBirdy were upstreamed (#17283) and should be part of Thunderbird 78, so they can be dropped from the patches we apply on top. Those are:
  • config/chroot_local-includes/usr/share/tails/build/thunderbird-patches/Avoid-local-timestamp-disclosure-in-Date-header.patch
  • config/chroot_local-includes/usr/share/tails/build/thunderbird-patches/Avoid-spellchecking-language-disclosure-in-Content-Language-header.patch
In the upstream patches, the pref mail.mime.avoid_fingerprinting was split into two new prefs, which have to be enabled instead:
  • mail.suppress_content_language
  • mail.sanitize_date_header
