..but only when not taking extra redirects or invalid certificates.
In other words:
"Make things as simple as possible, but not simpler."
Google has proper HTTPS on www and non-www.
On both www/non-www, /chrome redirects to a localised version at
https://www.google.com/intl/LANG/chrome/browser
This url without www is a 503 server error.
Firefox has proper HTTPS on www and non-www.
firefox.com and www.firefox.com have an invalid HTTPS certificate (www.mozilla.com)
and points to a completely differrent service (something LDAP).
On both www/non-www, /firefox redirects to a localised version at
https://www.mozilla.org/LANG/firefox/new/
Apple has proper HTTPS on www and non-www,
but their non-www redirects to HTTP www.
Prefer HTTPS and shorter urls

Turns out, getting it right.. is hard.
Oh, and for fun, worst case scenario:
