I never thought of that as the reason that Firefox became popular (and why Mozilla was quickly becoming popular before that). Back then, Mozilla's built-in popup blocker blocked nearly all popups. IE didn't have any corresponding feature? That sure would be a compelling reason to switch browsers!
When I read the article, the thought I had was that I installed AdBlock Plus only to disable the popups that Firefox didn't block with its built-in blocker when popups evolved to get around it. Is there still not an ad blocker that blocks only the most annoying ads such as popups?
