The chrome extension at least seems to break a lot of sites. They're not kidding when they say it's alpha.

Pages include resources from https-everywhere'd domains and for whatever reason (mostly that the ssl versions of those resource urls aren't serving the same resources, or have broken certs) those resources fail to load. Within an hour of using it I'd seen it break 3 or 4 sites, so it got disabled.

You can manually disable it for individual sites, if you recognize that it's the problem, but if some minor resource fails to load it might not be obvious.

The reason the extension 'breaks sites' is because an alarming number of sites are happy to serve unsecure content all over the place. See the refernece to New York Times in the original article for an example.
