Zero-Day Flaw In Firefox

ZDNET is reporting that an attacker can take control of your Windows, Apple, and Linux computer by the use of malicious JavaScript. This is a fairly new flaw, and there is not much assurance if this is true or not.

But to be safe,

The only fix at the moment would to disable JavaScript. To disable JavaScript in Firefox go to tools>>options>>content>>uncheck enable JavaScript.This will probably make alot of sites break in that case use NoScript a browser extension where you can choose what sites use JavaScript, and what sites don't use JavaScript or temporarily enabling JavaScript for a site.

By doing the steps listed above you will be protected against this Zero-Day and other unknown JavaScript exploits.
