This is where you make those annoying pop-up or pop-under ads work for you.

For example, I know www.aol.com always pops up an annoying ad. So does www.nytimes.com.

Instead of ignoring or closing them like you usually do, click on the ad. That will often cause a new browser window to open up. What you can't do, as an user logged on to the O/S, the software pop-up can!
