Top 10 Firefox Add-Ons
They take a look at NewTabURL, an add-on that will save you the frustration of searching for a way to open a web page on a new tab---because by default both MSIE and Firefox display a blank tab whenever a new tab is opened. Problem solved!
Other useful add-ons that are covered include the Web Developer add-on, which lets you "test, inspect, or troubleshoot cookies, forms, images, and many other web components" and the PageZipper add-on, which will "automatically load and stack next web pages in the browser so you see a continuous stream of content." Useful tools for both the developer and the end user.
