How to Grab a Screenshot of an Entire Web Page
Web designers and marketers often need full-size screenshots for before-and-after shots and also for portfolio pieces. Fortunately, there’s many ways to create website screenshots. However, among all of the options, my favorite way to make full-length screenshots is by using Screengrab! — a Firefox Add-on.
Using Screengrab! is about as easy as it gets. Simply bring up the page you want to grab and then click on the Screengrab! icon on the status bar.
The result is a full-sized screenshot of the Web page. I used it to take a screenshot of Snipplr, our public code snippet repository for designers and programmers.
