As of 13:48 pm Saturday east time in the US, Mozilla has recorded 15,353,384 downloads of its Firefox 3 web browser, the world best of its kind.

The company launched the new version on Download Day Tuesday hoping to make a Guinness record high volume of downloads in a single day.

The first 24 hours actually registered more than 8 million downloads, surpassing the expected 5 million.

There are more than 1 7,000 changes made to improve the user experience, security and performance of the free, open source software, the company says.

Mozilla tells supporters on its website that it takes a few days for the Guinness fella to review the documents on the download record and make an official announcement.

Some people say the attempt to create a Guinness World Record for most software downloaded in a day is silly.

Regardless, at least those who have tried Firefox 3 may have known that the product resulting from efforts from thousands of contributors provides a faster downloading speed.

The company says the download speed can be two to three times higher compared to its predecessor.
