Barnes & Noble ruleset triggers MCB
Using Firefox 23.0.1 with HTTPS Everywhere 3.3.1, the Barnes & Noble website does not work properly. Specifically, visiting the home page at http://www.barnesandnoble.com/ works fine, but visiting pages like http://www.barnesandnoble.com/u/books-bestselling-books/379003057/ fail, in part at least because images pulled from imagesbn.com no longer load. Disabling HTTPS Everywhere fixes the problem. Alternatively, disabling the "Barnes and Noble (partial)" ruleset also fixes the problem.
BTW, I have incorrectly flagged this report as applying to HTTPS Everywhere 3.4.1 because this bug reporting system doesn't seem to even know about the current 3.3.1 release.
