I'm using a note 3 N900W8 running 4.4.2 Using regular firefox or firefox beta for android. Some sites load but don't render anything. Opera, chrome, stock browser have no issues If I select to display desktop mode only the mobile site loads but nothing displays. The examples I have are major retailers in canada www.bestbuy.ca redirects to http://m.bestbuy.ca www.futureshop.ca redirects to http://m.futureshop.ca/ Bestbuy.com loads only desktop site but it loads everything at least
