A quickstart guide is available for ScriptNo here


Once you've installed ScriptNo, a lot of websites appear broken because it is preventing scripts from running. You might want to fix that for trustworthy sites that you visit frequently. To do so, right click the ScriptNo button at the top right hand corner of Chrome, and click on "Options". You'll see a field that serves as both a blacklist or whitelist, depending on which button you press. You can adjust it on-the-fly as you encounter "broken" sites.

Social Media Blacklisting

ScriptNo provides a unique "antisocial mode" that is available from the ScriptNo options menu. If enabled, it will remove social widgets/buttons, such as Facebook's "Like" button and Google+'s "+1", even when you're on a whitelisted site.
