Is it possible to (safely) synchronize preferences and add-ons across computers?

If so, how does one do this?

You can copy your Zotero profile folder from one computer to another to copy the settings and extensions over

Just to clarify: I'm not talking about copying but actually syncing back and forth, potentially with Zotero open at the time on each computer.

My concern comes from reading this page:
https://www.zotero.org/support/sync
which suggests that syncing in this way could cause data loss.

But I guess they are talking about the "data directory" (~/Zotero on my machine) whereas the profile files that you are talking about is in a different directory (~/.zotero on my machine). Am I understanding all of this correctly?

I don’t think it should be a problem to sync these (not like the Zotero data directory). But @dstillman would be able to say more.

I wouldn't particularly recommend syncing it. You wouldn't run into anything as serious as the database corruption you'd get doing this with your Zotero data directory, but you could easily run into problems, particularly if you're not careful to close Zotero on one computer before opening it on another.

In particular, there's a lock file (.parentlock) that gets created when Zotero is open, so you might be unable to open Zotero without deleting that file manually, and if you do that you may lose settings or corrupt files in the profile. Everything in the profile directory can always be deleted and recreated, but Firefox (from which the profile system is borrowed) does create that lock file for a reason.
