Mozilla has released Firefox 3.6.2 almost a week early after security issues were found in earlier versions.

摩斯拉几乎提前一周发布火狐3.6.2浏览器，因为之前的版本存在安全漏洞。

The Computer Emergency Response Team warned about Firefox 3.6

Firefox 3.6.2 was originally due to launch at the end of March, but is available to download now from the Mozilla website.

The security hole had led the German government to issue a warning about Firefox 3.6.

The Federal Office for Information Security made a similar ruling（裁定，统治） on the safety of Internet Explorer in January.

It warned that the Firefox vulnerability（弱点） , confirmed by Firefox makers¹, could allow hackers³ to run malicious⁴ programs（恶意软件） on users' computers.

Germany's official cyber-security response team - BurgerCERT - had recommended that users stop using Firefox until the tested fix was released.

It was a move remarkably⁵ similar to the January announcement, in which France followed suit（学样子） just days later.

Fox swap⁶?

The original Firefox vulnerability was confirmed by maker² Mozilla last week on its security blog, when it promised that the next official release would address the issue.

It is only the current version that is affected⁷ but, given that（考虑到，假定） prior releases have different vulnerabilities, reverting⁸ to an older version of the browser⁹ is ill-advised（欠考虑的，没脑筋的） .

Switching to a different browser may not be a good solution either, said Graham Cluley, senior technologist at security firm Sophos.

"Switching your web browser willy-nilly（犹豫不决的） as each new unpatched security hole is revealed could cause more problems than it's worth," he said.

"What are you going to do when your replacement¹⁰ browser itself turns out to contain a vulnerability?

"My advice is to only switch from Firefox if you really know what you are doing with the browser you're swapping¹¹ to. If you stick with Firefox, apply the security update as soon as it's available."

A Mozilla spokesperson said: "Last week we informed our users that the upcoming security release of Firefox 3.6.2 would include a fix for an exploit that was disclosed to us just over a week ago.

"Mozilla is aware of the BergerCERT recommendation to avoid using Firefox 3.6, and encourage users to download... Firefox 3.6.2."
