FYI
We're sending out this unscheduled emergency bulletin to alert you that there is a 0 day vulnerability in the wild that affects Firefox web browsers and the Tor browser bundle. The vulnerability emerged a few hours ago.
We recommend you temporarily switch to a non-firefox based browser until the Firefox dev team has a chance to release a fix. That should happen quite quickly.
We would like to encourage you to share this alert with the larger web community. It's unusual for us to send out a non-WordPress related vulnerability, but the impact of this may be wide-spread. We also suspect that WordPress websites may be used as a watering hole to infect vulnerable web browsers using this new exploit.
