> If someone steals the Firefox sync database now, and some part of the encryption scheme is later broken by e.g. quantum computers, the thieves could retroactively decrypt your sync account data. Since cookies and sensitive site data aren't a part of syncing, I guess I could see this being pertinent to your point of data being used to identify you. That being said, if I were a malicious actor, this sounds like a really low reward if you manage to compromise/crack encrypted Firefox Sync data. Ultimately, I agree with your point of reducing information exposure by self-hosting. My line of thought was more wondering what arguments there were on why this may or may not be worth setting up.
