HTTPS E breaks shopping bag HM.com
The rule for the website HM.com prevents you from adding products to your shopping bag on HM.com. When you say 'add to shopping bag', a loading animation in the middle of the site pops-up and keeps rotating but nothing happens. And in the shopping bag, no items have been added. When you shut HTTPS E down or disable the rule for HM.com, the site behaves like expected. Tested with FF 23.0.1 and HTTPS E 3.4.1
Also cross checked with IE, without of course HTTPS E. With IE you get a mixed secure content notification and only after you agree to still load the page, your product is added to the shopping bag. So my guess it's got something to do with this behavior, HTTPS E interferes in the process of correctly loading the product pages and delivering information to the shopping bag. Wrong URL (codes), HTTPS E wanting to do something the site already tries to?
