Mac/PC Firefox+bookmarks+extensions+cookies on a USB drive

Sam sez, "I have just finished putting together my cross-platform (Mac and PC) version of John Haller's Portable Firefox. With this you can store all of your bookmarks, cookies, extensions, plugins, and just about all your other browser-related files on a USB drive, and access your files and settings easily on every computer you have to use."
