8’290,908 is the exact number of Firefox 3 downloads, give or take a few thousands, with a strong 12 thousand downloads per minute rate at the time the mark was crossed.
In fact, the push was so hard that NetApplications reports it moved the market share needle by about 2% for Firefox 3: from around 1% early in the morning to about 3% by late at night.
Unsurprisingly, the United States is the country generating the most downloads with about 2.5 million, followed by Germany, Japan, Spain, the UK, France, Canada, Brazil, China and Turkey.
The number has yet to be validated by Guinness officials and hopefullly it will be included in the next printed edition of the Guinness World Records.
Edit: Poland, Lituania, Iran and Italy, all have more downloads than China and Turkey. I initially thought the list included the top 10 countries but it’s not the case. Thanks Paul for the heads up.
