Does Firefox VPN encrypt the SNI (Server Name Indication) like other consumer VPN's?
I want to know if Firefox VPN offers the same SNI protection as a VPN, and if my ISP will be prevented from sniffing my SNI and thus finding out the sites I visit even if I use encrypted DNS/DoH.
Why does DoH not work with the VPN? dsncheck.tools says my DNS is Fastly even though I have Cloudflare set in the DoH settings?
The VPN also fails a bunch of the checks on dnscheck.tools.
