Mozilla to Patch Critical Firefox 3.5 Vulnerability
Written by Vygantas Lipskas on July 15, 2009
Soon enough we will see Firefox 3.5.1 release as Mozilla is working hard to fix the critical security flaw.
Meanwhile, you may temporary mitigate it by disabling JIT in the JavaScript engine, to do so:
Type about:config in the location bar
Search for javascript.options.jit.content, double click it to set it to false.






Firefox 3.5.1 released July 16, 2009 11:37 PM and I just updated. Feels a little faster and more stable so thats a plus. :)
