AdSweep is a user script that blocks a good number of ads on some major websites, and works from a simple file you plug into your Opera or Google Chrome files. The instructions for installing the single AdSweep.user.js file in your Opera or Chrome browser are laid out step-by-step on AdSweep's main page. Opera users have a mostly graphical process, while Chrome users will have to check their version and then make a few tweaks to enable user scripts. The site notes that AdSweep will work for Firefox as well, along with Safari and Internet Explorer with some third-party add-ons, but each of those platforms has their own ad-blocking solutions, like Firefox's uber-popular Adblock Plus. Chrome users can also use a proxy solution like the previously detailed Privoxy to get annoying ads out of their way. We have to say it—the site you're reading right now is, of course, supported by advertising, and we'd ask that you keep them displayed if you dig what we do here. But AdSweep is pretty easily tweaked with, since it's just one file, and can be used for blocking of extremely annoying ads. It's a free download, works where Opera and Chrome can install.
