(Reuters) - Mozilla, developer of open-source Web browser Firefox, said on Wednesday it set a new Guinness World Record for the largest number of software downloads in 24 hours.
Over 8 million people downloaded Firefox 3 in the period following its official launch, the company said in a statement.
Mozilla is in a battle with Microsoft, which unveiled an experimental version of its Internet Explorer 8 in Las Vegas in April and has been looking to expand its presence on the Web.
