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, 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 22.214.171.124 should beware that there is a compatibility issue, but one of the comments in the Alexa blog post tells how to bypass the problem.
