Firefox 1.0.4 is a security update that is part of Mozilla's ongoing program to provide a safe Internet experience. We recommend that all users upgrade to this latest version.
Here's what's new in Firefox 1.0.4:
MFSA 2005-44 Privilege escalation via non-DOM property overrides
MFSA 2005-43 "Wrapped" javascript: urls bypass security checks
MFSA 2005-42 Code execution via javascript: IconURL
3 fixes worth having if you ask me!
