User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:44.0) Gecko/20100101 Firefox/44.0 Build ID: 20160123151951 Steps to reproduce: opening a link in a new tab (middle click) for a website that takes a bit of time to load to notice the problem (ex: facebook) Actual results: If I start typing a new url/search right after the tab opens, when the page finishes loading, the address bar resets the the original url content Expected results: The address bar should take the link address as content when opening but not reset to it once again when the page is finished loading
