Hi,
I’m interested in learning more about the “built-in VPN” feature (internally known as IP protection, I believe). Is there any documentation available other than the support article ( Use built-in VPN in Firefox | Firefox Help )?
Given that this seems to be using MASQUE as the underlying protocol, and Fastly as the service provider behind it, it would in particular be great to know
- If it uses a setup like iCloud Private Relay where there’s nested encryption and administrative separation between the “ingress” and the “egress” provider
- How authentication is implemented (i.e. whether that’s done using some privacy-perserving protocol like blind signed tokens, or whether it’s using an identifier persistently correlated to the user’s Mozilla account)
Thanks!
