Firebug 0-day Vulnerability

Note: A series of vulnerabilities were discovered and fixed in Firebug last night – it is very important that you upgrade your installation of Firebug immediately.

How to upgrade:

  • Go to Tools > Add-ons and look for Firebug. If the version listed is anything but 1.03, then you’ll need to upgrade.
  • Click the Firebug entry in Add-ons and click the “Find updates” button below. An entry for Firebug 1.03 should show up. Install it and restart Firefox.

Within 24 hours all Firebug users will be receiving the upgrade – and it will be installed the next time they restart their browser. Regardless, it’s important to get this fix installed right away.
