Mozilla have pushed out an urgent Firefox 3.6 update, which closes a critical security issue.
It’s the only change for Firefox 3.6.3, which closes a hole that could potentially allow remote code execution after a user visits a site with the infected code.
Full details for Firefox 3.6.3 can read in the release notes, including more detailed information about the fixed security issue.
Firefox 3.6.x users will receive a notification from the browser when it is ready to be updated, or it can be downloaded directly from the Firefox website.
