I wonder if they’re using my data to something or spying on me.

Because I use Firefox Sync to sync mostly my history. I don’t have bookmarks, I just remember what site I want to access by its URL then I start typing and the autocomplete do the rest.

For example, to access Lemmy I just type “le” because the only site I most access and starts with “le” is “lemmy.world”. Rarely I get some conflict on this approach. And it works on both my phone and desktop.

I wonder if should I change this approach to avoid Firefox Sync or I can trust on Firefox Sync.
