TL;DR: Mozilla is now enforcing data collection as a pre-requisite to access new features in Firefox Labs. This is backed by the Terms of Use that Mozilla introduced a few months ago.

Personally, I’ve been sharing this folder across different installations for years, even between different operating systems. I’ve never had any major issues so far.
The only minor annoyance is that whenever I switch between Windows and Linux I have to restart the browser once, otherwise extensions do not load on the first run.
So yeah, I would say diy-syncing this profile folder is feasible and very reliable. Same thing is true for Thunderbird, but I’ve been doing it for less time. And I would assume the same thing is also true for Chromium-based browsers because I do it with Signal which is Electron-based.
