Some good free popup blockers are AdwCleaner, AdFender and Ad Muncher. AdwCleaner works without installation, making it compatible with Chromebooks. This tool scans a computer for potential adware, undesirable programs and toolbars, and it lets users select the ones they want to clean and block.
AdFender runs in the background, and users can set up filters to block popup advertisements and cookies. It also features a history tab that lets users clear their browsing history. Ad Muncher provides options for users to filter various types of content including audio and adult content. Users can configure this software so that they receive a notification when the software blocks a popup.
