I was shocked to see the Firefox Devs recommending a third party add-on, Smart HTTPS. Smart HTTPS is actually pretty stupid, and does not include complex rulesets. The Electronic Freedom Foundation has spent a LOT of time making sure that hundreds of the most common violators of this issue are dealt with correctly. HTTPS Everywhere may not redirect everything everywhere, but it does fix even the most complex rule breakers, like Facebook. Check out this link and click through to the Facebook ruleset for an example. https://www.eff.org/https-everywhere/atlas/

The Electronic Freedom Foundation has spent a lot of time and resources developing this, and they should be congratulated. The author of Smart HTTPS should be ashamed, and ought to team up with the EFF.
