Let's say I search for something. I click on an item and look at the item then I walk away from the computer for a bit. I come back five minutes later and I have to hit the back button quite a few times. I think eBay's advertising keeps putting up a new sidebar ad and it's acting like a new page. Sometimes I can't go back far enough and I just have to click a new eBay page and start a new search. Please fix this eBay. It's really annoying.
Try adding an ad blocker from your browser.......that should stop any ads....... but I think I would run a malwares check also, just to be sure you don't have some kind of redirect program on your computer........
