The ads that appear on sites are usually created by third parties like advertising agencies or even individual product developers. We can understand that argument, and might even agree if the ads that appeared on sites were only negative in the sense that they are annoying or view-obscuring.īut ads can also contain malicious code and misleading information. Now some people would argue that ad blockers are unfair since adverts are the way web sites earn their money. After all, they slow down your browser, take up valuable screen space, and are often quite annoying. It might seem obvious why you would want to block ads from appearing on web pages you view.
