Chrome and Firefox use HTTPS first for sites in their preloaded HSTS lists. (I don't know if Edge has a preloaded HSTS list.) https://blog.mozilla.org/security

  > ut trying HTTPS first would be fantastic and eliminate one round trip for many of my sites that are not in the HSTS preload... It's almost as if you didn't read my post. Unless I can go register all my domains to be in the HSTS preload, I'd much rather Chrome tried HTTPS first, so I don't have to run a web server on port 80 that sends a 303 with https as the protocol.
