Ad And Stuff Blocker is an ad blocker extension for Safari. It is as simple as can be with no configuration - it just blocks ads. After it starts, a plain white window will come up and tell you that you are ready to start browsing. You can add URLs to the whitelist or close out that window and should never have to rerun the app unless you uninstall and reinstall Safari or OS X or you upgrade the app.
Unlike other other ad blockers that are not extensions, Browsing with Ad And Stuff Blocker is at least as fast as browsing without it - even faster if the page normally has lots of ads. We will never accept donations to whitelist ads.
Ad And Stuff Blocker now supports a user created whitelist and heavy duty ad blocking support for popular porn sites.
