Mozzila achieved a huge milestone. I billion add-on has been downloaded from addons.mozilla.org. It is to be noted that thay have started keeping track since 2005 and only downloads from addons.mozilla.org has been included in this number. 1.5 million add-on is being downloaded per day according to Mozzila.
I am a fan of Mozzila add-on. I am using many add-on and they are really nice and helpful in browsing experience.
