However, Firefox users should be aware that hackers can exploit software flaws and design features to launch drive-by attacks.
The following configuration changes, recommended by CERT/CC, can disable various features and set up the browser to run in a secure state, limiting the damage from malware attacks.

[UPDATE: July 10,2007 @ 9:25 AM] As a few readers have pointed out, these CERT/CC recommendations came from an older version of Firefox. On newer versions, the display screens will vary slightly but the advice/recommendations still apply. I was aware of this and spoke to Will Dorman of CERT/CC before this posting. He is updating the document to reflect the latest browser versions but, as noted before, these tips still apply, even on fully updated browsers.
