Mozilla Pushes Out A Critical Firefox Update

Grab it now.

As web browsers become increasingly complex with more features added (as well as APIs) every month or so, creative people find new ways to exploit them.

The latest example comes from the built in PDF viewer in Firefox, which was hacked, allowing attackers to browse through your local files and upload them to the remote servers if needed. In addition to that, once the script was executed, it removed itself from the system, making it harder to detect by the consumers.

Fortunately, the mobile version of Firefox was not affected as it lacks a built in PDF reader, so the only version you need to update is desktop.
