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.
So they know it’s you all the traffic comes from?
They also know it’s you when you don’t use it. I’m not sure how is it worse? Seems like a handy way to go around geoblocks.
Uhm, what? Maybe my ISP knows, but they are regulated (at least here). But VPN is a virtual direct-line to another server.
