There are no pop-up ads for me right now. I have Windows XP SP2, so I just use the one that's built into the browser.
The only ads are the ones that are at the top of the page and bottom. I've tried refreshing using just the F5 key and Ctrl + F5 and still none.
After the revert, even with the blocker, I was receiving an ad every page refresh and getting script errors. Now, none.
