Technically Speaking

Firefox 1.0.5 security update has been released. About a dozen security exploits have been addressed including issues relating to remote code execution through shared function objects, node spoofing, javascript prompt origin spoofing, a “same origin” violation, code execution using the “Set as Wallpaper” function, and frame-injection spoofing. So as you can see this is a pretty serious patch. You get it here — Firefox 1.05

But it is a time for many to patch their products;
“It’s been a hectic day on the security patching front. Microsoft’s bulletins for July include patches for three critical vulnerabilities on the same day that Mozilla releases new security updates for Firefox and Thunderbird. Not to be left behind, Apple fixed two Tiger flaws while Oracle issued a critical database server update.”
