A useful tool that let’s you take your online bookmarks with you no matter whose computer you’re using is Xmarks. (Formerly known as “foxmarks”)  Currently, Xmarks supports Firefox, Internet Explorer, and Safari for the Mac.

xMarks takes your bookmarks and syncs them across multiple browsers.  If you use more than one machine (work, home, laptop), you’ll always have your bookmarks with you.  OR, if your hard drive crashes, you’ll have your bookmarks just by signing into xMarks.  With xMarks, you’ll never have to remember a website, it’ll just be there in your well-organized bookmark bar.
