I was referring to Mullvad specifically, not Mozilla.

But Mozilla uses the same infrastructure in a partnership it seems. Again, not sure if its any good. I heard there were less servers overall (like half) than mullvads available servers, and Mozilla's privacy policy notes a fair amount of dara points they collect. Not that i would distrust them, just that mullvad doesnt even take an email address from you. They generate a unique ID for a new account. Payment there is the only data point, but they have crypto and were working on payment methods that didnt involve paypal/credit cards.
