dear firefox, i really think you guys should improve your "block pop-up windows" feature. because it doesn't seem to have the efficacy to stop pop-up ad windows. of all those updates and appearance changes, it's hard to believe that the feature haven't been improved and still cannot repel pop-up ad windows. forgive me that i had to ask, but please be honest, did those ad companies pay you in any way to stall or hold back your research in pop-up blocking, and to keep you from developing a "block pop-up windows" feature that actually works? please consider. thanks.
