If you don't want even the site you are browsing public, HTTPS is not
the solution.  Without SNI, HTTPS is one-site-per-IP (nobody uses the
subjectAltName to host multiple different sites on the same IP in
practice), so all somebody has to do it fetch the certificate from the
same IP/port and look at the CN/subjectAltName.  Either that's the site
you went to, or you accepted the host/cert mismatch (and are a target
for spoofing).

I don't speak for anybody but myself - that's enough trouble.
