Hello AnnaCN, Could it be that you are talking about the link to a site, that is now above the search result title ? If so, please see this thread : https://support.mozilla.org/en-US/questions/1276871 If you want to know why Google leaves out the "https", you should ask Google, but you'll see that when you click on that address, Firefox will add the "https". (Since a couple of hours I am part of that Google experiment too ... )
