Firefox’s free VPN will offer 50 gigabytes of monthly data, which is pretty generous for a browser-based VPN. A Mozilla account is required to make use of it, which isn’t a hardship (they’re free), but is a point of friction some may wish to know upfront.
How much does your VPN cost?
Also, whatever Firefox puts out there is not gonna be slower than TOR which has 3x the encryption and routing overhead of a typical VPN and also has no SLA guarantees at all. There’s a reason a middle-ground exists between no tunnel and mega 3x tunnel, and there’s nothing wrong with saving a few bucks if all you want to do is not be as profitable to data aggregators
TL:DR; stop making shit up
oopsy I don’t know not a big fan of browser bloating up, Ig I am wrong though my past experience with free vons weren’t that good, and I always ended up using tor.
