You were probably just opting out of Google's personalized ads, which means you still get ads, but they're just random. Those ads are only going to be the inline ads you might see during a Google search, or in your Gmail. It doesn't have anything to do with popups.
The way to BE more "clearer" is to tell us:
1. Your device
2. Which version of Android it's running
3. What kinds of ads you're seeing -- i.e., popup ads, video ads, etc.
4. What you're doing when you see the ads -- i.e., only while using the browser, or even when on the homescreen or within another app
See? You could've been much more "clearer."
