This is the "classic" official del.icio.us extension, updated to work with Firefox 2.0.
It offers everything you need to seamlessly integrate the del.icio.us service with your Firefox browser. Included in the extension are two buttons which allow you to easily post items to del.icio.us, and access your saved items from del.icio.us. In addition to the buttons, the extension allows for right-click posting functionality. A del.icio.us menu is also installed which allows for quick access to common pages on del.icio.us as well as keyboard shortcuts. The extension also installs the del.icio.us search plug-in right into the existing Firefox search toolbar.
Please note that del.icio.us also now offers a brand-new extension called "del.icio.us Bookmarks" which integrates even more deeply with Firefox's native bookmarking functions. If you would like to try out this new extension, please visit:
