According to the Mozilla Developer's Calendar, the company has postponed the launching of Firefox 2.0. Various reported vulnerabilities have pushed the official launching date as far back as October 24. The flaws were discussed in a status meeting and are related to the refresh function, panel customization, tab overflow, and to the spell-checking and anti-phishing features. The vulnerabilities were identified via beta testing feedback and through the results of the Coverity's Prevent bug-checking technology.

Mozilla locked down Firefox 2.0 Beta 2 in a code freeze on August 16, and the browser will see an intense period of testing, prior to its release on August 23. An estimated 40 vulnerabilities expect addressing before Firefox Beta 2.0 will be made available for the general public.

While initially the Mozilla browser had been scheduled to hit the market this month, the flawed aspects of the application interfered with the plans. Mozilla decision to push back the release date and to launch anther Beta variant of Firefox 2.0 is meant to deliver almost a month of additional testing feedback to bulletproof the final version.
