Windows only: Jump Lists are one of the best new features in Windows 7, and since Firefox still doesn’t take advantage of them, a small utility called Winfox adds the feature for you.
Using the utility is simple enough—just pin Winfox to your taskbar and you’ll have a new Firefox icon with an enhanced context menu—you can open new tabs, view your most frequently visited pages, pin items by simply dragging and dropping, and the items even display the favicon of the page. It’s one of those features that most likely will be included into future versions of Firefox, but for now it might be just what you’re looking for.
Winfox is a free download for Windows, and both 32-bit or 64-bit versions are provided—you’ll want to make sure to pick the appropriate one for your version of Windows. For more, read about Windows 7’s best underhyped features like using middle-click to close applications. Thanks, Shankar!
