HP windows vista need a free pop up blocker what is my best choice thanks Jackie
If you mean for internet browsing use, it's in the browser. For a true pop-up blocker, google that with your browser name, like
pop up blocker firefox.
If you're interested in an ad blocker, same approach
ad block firefox
pop up ads are very annoying and you can stop them with what snidely said. Keep in mind that *sometimes* you will need to disable it for certain websites, e.g. they are not always bad, just most of the time.
to block ads and pop ups while browsing use ad blocker plus extension. It even blocks ads on youtube. Search for it on extensions in firefox or chrome
