Sparky: Alexa comes to the Firefox browser
This was just released yesterday, I think. Alexa has finally released its official toolbar for the Firefox browser, called Sparky.
Unlike in Internet Explorer, the Alexa toolbar for Firefox will be added at the bottom of the browser, right side of the status bar. By default, it shows a rank of the domain/site you are currently browsing and a small graphical trend in the last 4 months.
Note: Alexa toolbar is often flagged by anti-spywares and anti-virus softwares as spyware. It’s primarily because the toolbar sends usage data/information back to Alexa (phone home).
In any case, this will increase the relevance of the Alexa rankings as it now covers more browser species.
