Do you folks mean the page being redirected and ending up with a nearly blank page, with a little advert bar up at the top left, with no way to go forward?
That has been happening to me for a few months. Repeatedly, and regularly. It makes using the site pointless at times. Pop-ups are one thing, you can get around them. Having something that completely rejects the option to go through to the link I click on and stop dead at a banner ad on a blank page every time I click a link is completely another. It interferes with posting and simply viewing pages much of the time.
However, I must say, that using the tabbed browsing through Firefox does sometimes circumvent this problem. I have started to right click and click "Open new tab" on this site now. It cuts the interferance down by more than half usually.
