Website rating system, Alexa.com, a subsidiary company of Amazon.com recently announced that their popular toolbar is now available for Mozilla Firefox. The announcement was made on Monday on the Alexa blog^[1], but I did not notice it until today. The new Firefox Alexa Toolbar is called Sparky.

Below is a screen shot of how it looks when installed. The screen shot was taken from the Sparky download page.

I used to have Smart PageRank Toolbar 1.0, but consider it gone now. Users who have Mozilla Firefox 2.0.0.5 should beware that there is a compatibility issue, but one of the comments in the Alexa blog post tells how to bypass the problem.
