Some days ago i wrote about Better Bookmarks in Firefox 3 and someone mention del.icio.us service. So now you can use this with Firefox 3.

For all of you that already use Firefox 3 i want to

announce a beta release of an enhanced version of our Firefox Add-on for del.icio.us that now has full Firefox 3 support while retaining Firefox 2 compatibility.

Now with this plugin you can:

* Jump to Tag feature (press F2) allows you to quickly access tags and
bookmarks using the keyboard
* New layout for saving bookmarks
* Preferences now in a separate dialog under Tools (which also can be
invoked via the prefs button on the FF Add-ons pane)
* Status bar indicators for network activity, new links for you, and the del.icio.us website
* Classic mode for users who just want simple buttons without the overhead of sync
