If you use Firefox sync, then your sync identity is leaked across all containers.
This makes you identifiable across containers and subverts the whole idea.
So don't use sync.

Interesting. From the response at bugzilla it seems that the feature is built on top of "FF accounts" (which I'll have to look into) and that the browser communicates directly with the Firefox sync servers. Meaning that only Mozilla would know your sync identity across containers. Did I get that right? Whether that's a privacy concern is something that I'll have to think about. What's your take?
