Basically I am using mull on android and librewolf on linux.I want to use firefox sync or something line that for syncing.So how good Firefox sync is, in privacy point on view. I am not anonymity paranoid I just want privacy so basically what do they collect and for what?
Great setup btw
Regarding your question: Firefox Sync is end to end encrypted, so you don’t have to worry about it. It’s far better than Google’s browser sync, as it’s encrypted at all (only in transit, but this is standard and it means that Google can still see all of your data)
