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.
Same as every other vpn???
Other vpns aren’t integrated into your browser that you’re globally logged in into.
Nah just integrated in your machine
