Firefox aims for download record.
Version 3 of the popular Firefox web browser is going on general release on 17 June.
Wide take-up of the new version would further boost the market share of the browser which is currently used by about 15% of net users.
With the release, Firefox developer Mozilla is attempting to set a record for the most downloads over 24 hours.
"It's a global effort to make history," said Paul Kim, head of marketing at Mozilla.
Net gains
So far Mozilla has not said exactly when on 17 June the attempt to break the record will begin.
"There is actually no record for the greatest amount of software downloaded in one day, so for 24 hours from the moment we push the bits live, that's when the countdown starts," he said.
Mr Kim said Mozilla had no specific target for the number of downloads it would like to achieve on the day but racking up five million would be "awesome".
By comparison, Firefox 2.0 registered 1.6 million downloads on the day it was made available on 24 October, 2006. More than 1.3 million people have pledged to download the new version on 17 June.
New features in Version 3 include automatic warnings when users stray onto webpages booby-trapped with malicious code.
Also in Version 3 will be "Smart Location Bar" that lets people return to places they have visited even if they have not bookmarked them or cannot remember the full web address.
Firefox 3 will work with Windows 2000, XP and Vista and some non-Windows operating systems including Linux.
Mozilla is not alone in marking the release of the new software. According to the Mozillaparty website more than 566 celebrations are planned for when the software becomes available.
