For years, Alexa has been the home of stats..
Alexa measures traffic by the amount of people who use it’s toolbar in Internet Explorer.
That was fine until a few years ago when firefox came along.. the majority of us tech savvy geeks switched to the superior firefox and as a result Alexa’s stats were obviously flawed in many people’s eyes.
With firefox and alexa now working together, we’ll get more accurate traffic results. For me personally, it’s a good thing. Across all of my sites bar theleavingcert.com, the majority of visitors use firefox (probably because they’re the more educated, ‘with it’ user).
Alexa plays a small part in text link ads pricing and reviewme ratings etc.. so us webmasters should see a rise in our rankings 
The new plugin for firefox is available for download here.
