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.
But unlike the VPN server, the browser is on my end and i can make sure it doesn’t rat me out. Coincidentally, my policies.json over the years was almost the same as Waterfox’.
