works great with duck duck go's extension. These are the only 2 you need.

Please add a button (function) allow only HTTPS and block all http. Thank you.

Very good Addon.
I was using HTTPS Everywhere before which is crap (did not redirect to HTTPS on all websites).

Work in firefox 58.0.2

Nice addon, automatically checks if HTTPS works on a site, which works better than HTTPS Everywhere's manually updated ruleset.
