https://support.mozilla.org/en-US/questions/1073862 Removed after 38.1 back after 38.2 I am sure there are more as this was not the one I went looking for.1.) Not at the moment, as all production machines have already been updated and the testing machines have no internet connection, so over-installing is the only option. Maybe someone else could step in and test it with automatic updating in the meantime.The question for me is if this bug needs immediate attention and must be included in the next update, or if I can take a bit more time investigating this and figuring out a solution with the addon manager folks. Installed Thunderbird 38.0.1 in my test user account on Linux Mint 17.2 and created a test profile.
Over-installing a new version has always been a fully supported way of updating, so there's no reason to consider this more minor.
Unfortunately, all older releases, including Ubuntu 10.04 Lucid Lynx LTS, provide old versions of Thunderbird by default.
This page will explain how to install a newer version of Thunderbird.
By the way, I never asked for silently co-installing Lightning along with TB for ALL user accounts.
I prefer to install extensions on a per-user basis, as it has always been with both Firefox and Thunderbird.
For Ubuntu 10.04, it will explain how to upgrade to Thunderbird 3.1.
