I just installed a fresh Ubuntu Mate 20.04.4 LTS but Thunderbird is resisting my attempts to install version 78(.14 currently). It seems like Ubuntu only provides one version (the latest) through the software "boutique" (which doesn't actually tell you what versions it has of various software until after you install them).

Is there a straightforward way to install 78.14?

(BTW. just migrating from Windows...)

If you do not have a specific - and very good - argument / reason to need an old Thunderbird:

Then do install the one provided by sudo apt install thunderbird
(type that in a Terminal / Shell / at the Bash prompt).

This will (currently) install version 91.8.1 if I'm not mistaken, it will also be auto-updated when new versions or updates become available; depending only on how you set the update options [1].

Note: I would not expect it to cause any problems, even if using it for any files you have saved.

Note2: As a beginner Ubuntu / Mate user you will have the least problems if you restrict software installs to be via apt (as above), System software or any other means that uses ppa:s or *.deb files. Opinion: snap-package -installs seems flaky IMO, that might have changed after I stopped using them though.
And one more opinion of mine; Everything else is for advanced and experienced Linux users.

[1] hit the Win-key, type updater and Software updates will appear, click on it, it checks for updates and then; click Settings ... to set options. (Assumption: Mate works the same as "Ubuntu")

As @user535733 indicated in the comment above, you can download the archive from thunderbird.net, extract it and run the binary

  • Download the x86_64 version of 78.14 : https://download.mozilla.org/?product=thunderbird-78.14.0-SSL&os=linux64&lang=en-US
  • Unpack the .bz2 archive : unp thunderbird-78.14.0.tar.bz2
  • cd thunderbird
  • ./thunderbird
  • Under Preferences ... General in the Updates section set Allow Thunderbird to to Check for updates, but let me choose whether to install them. Otherwise it will auto update to a newer version and upgrade your profile (which can't be downgraded).

You're now running version 78.14 and it won't update to a new version.

If there was a .deb file for Thunderbird 78.14 you could use that but I've not found one.
