Windows/Mac/Linux (Firefox): Digg Navigation shoots you to virtually any area of Digg with just a few clicks.
Just right-click anywhere on a web page and scroll down to Digg Navigation. The fly-out menus are organized just like the Digg site: You can navigate to a specific category or jump directly to pages like DiggLabs, Diggnation and Search. If you want similarly fast access to profile pages, head to the Options menu and add your username and/or the usernames of up to 10 other Digg users.
Nice! If you frequent Digg, you'll undoubtedly save time by using this extension to navigate the site. Digg Navigation is free; it should work with any version of Firefox (though the developer doesn't specify compatibility—if you encounter a problem on a platform other than Windows, let us know in the comments).
