Five days ago, the Del.icio.us team announced and subsequently delivered the final version of that extension to the official Mozilla Firefox add-ons repository.  Be sure to check out the official blog post from the del.icio.us team detailing all the new features in the release: "Firefox 3, Delicious and You."

Overall, the extension provides a great way to keep your bookmarks (with tags and notes, too) synchronized on each of your computers and, of course, on your http://del.icio.us account.

(FoT Tip: If you’re a nut for synchronization, you should also check out the Mozilla Weave extension for Firefox.  In addition to bookmark synchronization, Weave also allows you to sync stored passwords, cookies, browser history and saved form data.  Check out what we had to say about that a couple of weeks ago.)

Microsoft devotees shouldn’t feel left out as the team has also announced and released a beta version of an add-on for Internet Explorer.

• keyboard-shortcut (Ctrl+B) activated search-as-you-type functionality
  (this brings up the sidebar which brilliantly disappears as soon as you find what you’re looking for)
• the ability to add both tags and notes to your bookmarks
• synchronization with your del.icio.us account (meaning that neither a specific browser or the extension itself are necessary to find your bookmarks – just hit http://del.icio.us while you’re on the road and login.)

This is one of the few tools that I use every single day and, unfortunately, it’s core functionality became broken when Mozilla released the beta versions of Firefox v3.  It’s taken quite a while but Yahoo! has finally released an updated version of the extension yesterday afternoon:

I found it took a bit of maneuvering to get to the installation file so I’ve gone ahead and posted it on our site for you to download.  Just save the file, open your Firefox Add-Ons window and drag-and-drop the .xpi in there.  The installation process will proceed and you’ll be prompted to download the update.

By the way, kudos to Yahoo! for listening to their users and pushing out an update to this extension.  The final version of Firefox 3.0 hasn’t even been released so they technically didn’t "have" to release a version yet but they realized there was a huge demand for it.  Are you paying attention, Google?  I only ask because it’s been almost two years since Google Browser Sync was released and very little has been done to keep it updated.  In addition, you’ll notice that almost every post in the Google Firefox Extensions newsgroup remains unanswered.
