Following video of thelinuxexperiment and all the news against mozilla.
I finally switched to librewolf completely.
I exported and imported all kind of data too.
But I want to use ffsync only to keep my mobile (android) in sync with my pc (want to sync history also so flocuss etc will not work)
So I want to enable ffsync in librewolf
I have seen faq but as mozilla recently introduced their terms of usage (and all the hate against it)
Is it still private enough to use ffsync? what can be downsides?
Yes, in theory, but in praxis no because self-hosting the sync server alone still depends on the centralized auth server from Mozilla, and self-hosting that as well is possible but complicated. It’s sadly a mess, and you might be better off not using Firefox sync at all.
As for your other question, depends on the specific addon, but usually no.
