Firefox 3.5.1 Fix for Vulnerability

Yesterday I wrote about a vulnerability recently discovered in the month old Firefox 3.5. The folks at Mozilla were quick to find a solution and have published a new build which is safe to use.

If you’re a Firefox users go to the following site to update your browser.

If you followed the instructions to disable the JIT(Just-in-Time) compiler you’ll want to enable it again once you’ve installed version 3.5.1.

1. Enter about:config in the browser’s location bar.
2. Type jit in the Filter box at the top of the config editor.
3. Double-click the line containing javascript.options.jit.contentsetting the value to true.
