been on this for a while now, to be honest if this doesn't get me the solution im going to use another browser. I don't have this issue with safari, I use a macbook. when i try to close tabs, a pop up remains, they are either a fake apple support window, or a mackeeper equivalent, or other financial things. Occasionally when I click on a link, it ignores the link and opens a pop up in its place. These pop ups are like normal windows rather than extra windows that run over - i.e they replace either a tab i am closing or act in place of one.
