The Gmail Manager is one of the simplest, yet one of the most useful addons for Firefox. Unlike MSN which pops up a huge box everytime you get an email, this just has a tiny little thing that sits at the bottom of your screen. It is red and says "0" when you don't have any messages, and turns blue and tells you how many messages you have when there are some. Furthermore, you can set it to check at whatever interval you want. So if you really want to keep on top of your email, set it to check every minute. If you don't care as much, make it 15, 30, or even 800 minutes. :)

So simple and so useful. That's exactly how an addon should be.
