keep on-the-ball and update themselves to this new version."
More information about the new version of Firefox, which is
available for Windows, Mac OS X and Linux, can be found on Mozilla's website.
Sophos continues to recommend computer users practise safe computing as well as running
up-to-date anti-virus software.
