Mozilla released the latest version of Firefox on June 17th amidst much fanfare and hype.  The major buzz about this release being the attempt by Firefox to break the Guinness Book of Records for the most downloads in a 24hr period for a single program. 

Well the launch has not gone so well for Firefox.  Firstly due to the number of people attempting to download the latest version (over 8 million) the site’s availability has been patchy at best.  But worse was to follow, within five hours of its release a security vulnerability affecting the latest version, and previous versions, were discovered.   Tipping Point have verified that the vulnerability is real using their Zero Day initiative.  The SANS Internet Storm Center and the Security4all blog provide more coverage on the issue.

For the browser that promotes itself as being more secure than Internet Explorer this is not the best of starts.
