I’d love to be able to snyc everything (all settings, including user.js, etc.; all extensions and all of their configuration; all visual changes, including userChrome.css and additional files; all website configurations, including all cookies). Basically a 1:! copy of the user profile directory.
This won’t happen, though.
I could write a wrapper script that synchronizes the directory between two Linux machines quite easy, yes. The script would even make sure that the browser is not running.
That’s a simple task, but not my point.
(Let alone syncing the data between at least 4 different operating systems running on 3 different device classes.)
I think Syncthing runs on most OSes now. You would just point at a folder and register the token for them and it does the rest.
