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.
If anyone missed them removing the “we will never sell your data” from their promise to their users, this is clearly their next step in monetizing their users.
