The in-depth comparative study into how browser security packages are updated discovered that Firefox's update mechanism is the most successful at getting users onto the latest version. Despite this, a steady percentage of insecure surfers - never lower than 20 per cent throughout 2007 - is always using an insecure version of Firefox.

By comparison, 54 cent of Opera users are relying on older versions of the web browser software.

The study - Firefox (In)Security Update Dynamics Exposed by Stefan Frei, Thomas Dübendorfer and Bernhard Plattner of the Swiss Federal Institute of Technology and Google Switzerland - is a follow-up to a paper published last year entitled Understanding the Web Browser Threat. The research is described as the first global scale measurement of the patch dynamics of a popular browser.
