I'd love to be wrong about this, but I don't see them as privacy oriented - only marketed as such.
Mozilla made it harder for me to handle my passwords. In their effort to not lose market share and to market themselves as ecosystem rather than a browser vendor, they did horrible things to their password storage. Sync1.1 was tolerable. Accounts+Sync1.5 is an abomination. It's bloated beyond reason, full of weird protocols and formats mixed in odd ways. I'm not even remotely a strong engineer but I can't call what Mozilla made there "good engineering".
And I spent some time writing my own implementation of Accounts and Sync, so I believe I can assure myself my opinion is not completely baseless but relies on some first-hand experience (my crappy code is not good engineering - but neither I claim it such)
