FireFox and Alexa

We've been getting a lot of requests to build an Alexa Toolbar for FireFox (nifty new Open Source browser.) Here's the party line(s):

1) We already built one. It is called "What's Related" and it was built into Netscape and Mozilla, but the FireFox folks have orphaned it. Send them a note.
2) Build one yourself. We have a feed. They have an Open Source browser. Build one!

In fact, it looks like some people are already playing with it here, here and here.
