600 Million Add-ons Downloaded from Mozilla

Mozilla hit a huge milestone the other day when the download counter for their add-ons rolled over the 600 million mark. That number only includes downloads from the add-ons sitea, and on top of that there are about 100 million update pings each day. The breakdown for the update requests are pictured to the right in the pie chart, and there are already more than 1 million update requests from users running pre-release versions of Firefox 3.
On a daily basis the add-ons site receives between 800,000 and 1 million downloads, and gets a whopping 4.5 million pageviews. All of that comes from people looking to get one of 4,000+ extensions that are currently hosted there.
