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?
It doesn’t sync addons and about:config, so there’s that.
Do you mean add-on configuration? Because I’m pretty sure it syncs add-ons… Or at least, it sure did for me.
Man, and it’s only half a year back i looked this stuff up…
I was working from memory too, lol. But can confirm: it does (have the option to) sync add-ons.
