Edit the web: alter any website inside your browser -- Every once in a while, I have to create project proposals focused on website content, and I get to pull out a very fun tool called Edit the Web. It's a browser extension that, once turned on, allows you to go to any website and edit it inside the browser, live! Of course, the edited site doesn't stay that way or look that way to anyone else. But this tool is super useful for creating quick mock-ups for screenshots.
