You need to export the profile and re-import on each machine. If you make any changes on one machine you want to see it reflected on the others.
The profile import is a bit iffy and there was some odd issues with downloading profiles over 2GB IIRC, the last time I did it (which was over 2 years ago).
There seems to be a lot of focus on features that IMO that I couldn't care less about and some outright stupid UI decisions like the context menus being changed after 20 years for god knows what reasons.
The result was that I just gave up and use Thunderbird on one machine and web-mail on all the others. I suspect I will just drop Thunderbird as a result.
I guess they mean that they want their accounts to be synced (setup is annoying tbh), but also things like signatures and so on.
I normally just manage it myself and I'm extremely happy to do so, as I consider it like my dotfiles, but I understand where the parent is coming from - settings sync is becoming common. (Chrome is a good example).
