The Mozilla Foundation has set a world record and achieved new heights in its battle for browser market share. According to the Guinness Book of World Records, Mozilla's Firefox 3.0 Web browser set a record for the most downloads in a day. It was the first time a browser-maker attempted to set a record.

Mozilla set the record with 8,002,530 downloads in June. The Mozilla Foundation will receive the official certificate in London next week.

Researchers from Google, IBM and the Communications Systems Group in Switzerland released a study Monday that shows only 60 percent of Web users are surfing with patched, updated browsers.

They estimated that only 576 million of 1.4 billion Internet users worldwide used the most secure browsers. The data came from Google's server logs between January 2007 and last month.
