Mozilla releases version 4.0 of its popular open source web browser Firefox today.
However, Mozilla also had to release an update at the weekend to patch two issues, which Mozilla director Mike Beltzner said "have caused us to take two very small, very isolated fixes in order to better protect Firefox 4 users."
Firefox 4.0 supports Linux distributions, Windows (including XP Professional, which Internet Explorer 9 does not support) and Mac OS X.
Mozilla Firefox 4's Peacekeeper benchmark is still 57 per cent slower than Google Chrome 10's Peacekeeper result though.
The latest statistics from browser NetMarketShare shows a decline in market share for Firefox of about one per cent over the January to February period, from 22.7 per cent to 21.7 per cent, which Mozilla will be hoping to reverse with Firefox 4.
