The latest upgrade to Firefox, dated 27 October, in particular for the Mac 3.5.4, has 6 “Critical Vulnerabilitioes” listed sine the September 3.5.3 update – See: Security Advisories for Firefox 3.5 – This rounds out to 25 Critical fixes since the June release of 3.5

Should you update? No question. Just look at the definition of Critical – Vulnerability can be used to run attacker code and install software, requiring no user interaction beyond normal browsing.

There will be confusion by those who have heard that there is a new release that is a beta. Do not be confused. A beta of 3.6 is iminent – it was expected on the 28th, but has been delayed.
