While I can appreciate the technical merits of this (and rauhl's valid criticism), Firefox Sync is simply something I don't want, no matter how securely it's implemented. I don't want anything to carry over between browsing sessions. Nothing. Not cookies, not super-cookies, not browser cache, not fonts. (About all I'm ok with carrying over is my uBlock plugin. There may be some other things like DNS cache and HSTS... though they're deeper than my realm of knowledge. I reckon keeping those are an acceptable trade for security vs tracking.) As much as possible, I want each browsing session to be fresh, as if I were starting the browser up in a VM, and then reverting state after closing. I reckon that makes it that much harder to track me across the internet. Firefox Sync seems to be an antithesis to this. (And I'm not very trusting of it's password saving feature, either.) However, given that YouTube's front page seems to be picking up on my interests, maybe my measures are ineffective. (No 3rd party cookies, clear everything after browser close.) Perhaps I should give up hope and just permanently stay logged in. (As an aside, one thing I was very sad to find out... I VEHEMENTLY DESPISE Firefox restoring all my tabs after a crash. If something evil caused the crash, I don't want to give it a second shot! ((Or worse, opening a browser in front of a coworker or client, and it restoring tabs I wouldn't want them to see. There's no warning or consent obtained, just... "HEY! Here's all your old tabs!")) However, disabling this feature ALSO disables "open previously closed tab", which I'm OK with. It seems a bit strange that these features are linked, perhaps someone can explain it to me.)
