Why do I get a empty pop-up tab when I use firefox?

When ever I start firefox, a few seconds later, another tab will open up on it's own and it is empty. I continually have to close it and then a few seconds later, it opens again. What ever the page is, it has a statement saying firefox has prevented this window from opening etc....with an allow exception. It does seem to be a pop-up but my pop-up blocker is on. I did uninstall firefox and re-installed it. Is it a setting on a certain website or is it in Mozilla? Thanks.....Jason
