Steven Frank created “shutup.css” a custom user stylesheet that can be applied to your browser to hide comments on many popular web sites without user intervention. The stylesheet blindly hides blocks with IDs like "comments", which could have unexpected side effects. Disable shutup.css if you think you might be missing important page content. To install, download the auto-updating shutup.css file to your system. If you don't trust a remotely-imported CSS file, or want to make customizations, you can download source directly instead. In your browser's preferences, configure your browser to use shutup.css as a custom user stylesheet. In Safari for Mac OS X, it looks like (see screenshot). If you make changes, or download a new version of shutup.css, quit and restart your browser to make sure it takes effect. Firefox users may wish to try Stylish plug-in. Charles Stuart provided a Chrome extension.
