Comment:

 I like the idea of supporting sync, because it's my understanding Mozilla
 more or less did it right, and it's end-to-end encrypted to the client,
 but I agree the pref change problem is bad.

 On the other hand, perhaps people who use sync should create a separate
 account for their TBB syncing?

 Either way, this does sound like a usability issue. I suppose we could at
 the very least inform people that they should only be syncing TBB
 profiles. Perhaps there's some sort of profile version negotiation we
 could make use of for this.
