The Yahoo! Toolbar for Firefox has been upgraded, taken out of beta and has been stamped with a shiny new version number 1.0.
Resize the toolbar's search box with drag and drop (useful), view your search history in a dropdown that expands to your longest query (helpful) and automatically add feeds to My Yahoo! with the Live Bookmarks icon on Firefox's status bar (VERY useful.) For big Yahooers, the toolbar is fantastic - especially for My Web and Mail users.
