Same thing for chrome too, I remember seeing a stat saying the two ad block extension were the two most popular extension on the web store. And then add extensions like ghostery and its ~500k users on chrome only, etc ... Those stats are never meant to be taken to the %, or even 5%. It only gives a raw idea of who uses what. You don't know for sure if firefox/chrome is 15% or 25%, all you know is that it is massive but not overly dominant.
