This pop-up blocker's middling performance keeps it from outdoing its numerous and more capable competitors. True to its name, FilterGate Free PopupFilter won't cost you a dime, but that's the most positive thing we have to say about it. In our tests, the program stopped only about half the pop-up and Flash ads we threw at it, a rather disappointing statistic. The interface is bland, but we do appreciate that the app can minimize to your system tray for quick access. This program offers most essential features for its class but doesn't provide you with anything special. You can choose to allow pop-ups by adding sites to a whitelist and specifying what types of ads to block. The log provides you with a list of quashed ads, but the app doesn't flash or emit a sound when doing its job. Downloading this free program certainly won't do any harm, but we question how much good it will really accomplish.
