3) Firefox and Thunderbird have been updated quite closely to the upstream releases even for old LTS releases.

4) Thunderbird got no update since 2018-07-03 (http:// changelogs. ubuntu. com/changelogs/ pool/main/ t/thunderbird/ thunderbird_ 52.9.1+ build3- 0ubuntu0. 18.04.1/ changelog) despite the new version 60. For upcoming Ubuntu 18.10 there even is an older version 52.7 version available (https:/ /packages. ubuntu. com/cosmic/ thunderbird). Debian Sid has a 60ish version (https:/ /packages. debian. org/sid/ thunderbird) that may be reused.
