Flashblock Alternatives

    Flashblock is described as 'takes a pessimistic approach to dealing with Macromedia Flash content on a webpage and blocks ALL Flash content from loading. It then leaves placeholders on the webpage that allow you to click to download and then view the Flash content' and is a popular Ad Blocker in the Web Browsers category. There are seven alternatives to Flashblock for a variety of platforms, including Mac, Windows, Linux, Firefox and BSD. The best alternative is NoScript, which is both free and Open Source. Other great apps like Flashblock are GNU LibreJS (Free, Open Source), RequestPolicy (Free, Open Source), 3P Request Blocker (Free) and Better Pop Up Blocker (Free).
