Many folks still don’t realize that the browser they are using at this very moment is designed to be customized. Chrome, Firefox, Safari, Opera, even Internet Explorer–all have some really cool and powerful add-ons (called extensions) that do countless things, from blocking annoying popups to checking spelling to making sites more easily readable for people with visual impairments. You name it, there is probably an extension for it. As a way of an introduction, I thought I’d share a screenshot of my own Chrome toolbar and the extensions that reside there currently (It’s a fluid list.). More Chrome extensions can be found here, and Firefox extensions here.
