Furl - Your web page filing cabinet:

"Furl is a new web browsing tool that lets you save and organize thousands of useful web pages (you know, the ones you want to save for future reference but then can never find again) in a personal 'web page filing cabinet'.

Once saved, you can effortlessly find any page again later using a powerful full text search tool. With Furl you can forget trying to save and organize dozens of bookmarks, forget saving web pages to your desktop, in fact forget everything except how to find a useful web page again next time you need it.
