Shortly after upgrading FireFox, whenever I try to go to a website, like PayPal or my bank or anything else, I immediately get a large Ad/site for something frequently related somehow. Like my bank I will get something suggesting an online bank, or ways to make banking easier. It will be a large window, covering my original window. I have to exit THAT site to get to the one I want. It is a separate window, I cannot just X it out, I must shut down that window. Then the window that I actually want will be beneath it. I can't figure out how to fix it.
