Barely five hours into the release of Firefox 3, the browser had garnered nearly 1.6 million downloads -- a number achieved by its very own predecessor - Firefox 2 - only at the end of one entire day. The Mozilla Web site continued under pressure, 9,000 free copies per minute and rearing to go -- to break that all new Guinness World Record for the largest number of software downloads in 24 hours.

Some place else though, Tipping Point's Zero Day Initiative announced finding the very first vulnerability -- also within five hours of the browser's release. The traditionbeing not to disclose specifics of a vulnerability until the vendor has had a chance to patch the same, yet, Tipping Point verified the vulnerability and rated it as 'critical'. A blog post said the vulnerability that also affects Firefox 2, could allow an attacker to execute arbitrary code if explored.
Tipping Point promptly reported the vulnerability to the Mozilla team, and the latter is said to be working on a fix for the same.

Vulnerability or no vulnerability, Firefox 3 has managed to break a new record, registering 8.3 million downloads in the very first day. Perhaps it's time for one more cake, is the Microsoft IE team listening?
