Let's get this straight. Yahoo can afford to kill a dozen products at once, but the Yahoo Toolbar -- a relic from the days when only birds Twittered -- just got a full makeover? Go figure. At least the browser add-on has received the same sort of tender loving care given to other recent Yahoo apps, including a fresh look, speed improvements and Chrome support. If you rely heavily on Yahoo services, or just have trouble letting go of the past, the toolbar update is available today.
