Alexa’s Toolbar has been exclusive for Internet Explorer for a long time. Finally they have made it available for Mozilla Firefox as Sparky. Amit Agarwal notes that it is more of a status bar though. Alexa is a traffic tracking site, which is primarily used to rate and rank sites. It uses the toolbar usage logs to build the metrics. However, they were skewed since the toolbar was available only for IE and hence they represented only the IE users. Will Sparky add the correction for Firefox users? I hope so. Of course, it is still necessary for you to go and download it to start using it.
