The Yahoo Search Blog announced that they have updated the Yahoo Toolbar. For IE users, you can use the toolbar to enable tabbed browsing in IE 5 or 6. For Firefox users, they have added for bookmarks, mail alerts, and AntiSpy for all countries that Yahoo supports (and no list of these is given).
In addition to those updates, they are now giving users the ability to tag content with del.icio.us directly from the browser. It is an optional feature that can be turned on by clicking here if the toolbar is already installed. If not, you can find the option under the Add/Edit Buttons page in the "Personal Tools" section. This move makes practical sense, since Yahoo Acquired Del.ico.us. Oh, you know del.icio.us is hard to spell, when Yahoo has a typo in the blog entry ("del.icio.us ito save").
