Chrome and Firefox have a plugin architecture and don't have ad block built-in as shipped. Huge difference there.
(On a sidenote I'm still using Firefox over Chrome as Firefox is still the superior adblock platform. ;)

What difference? Safari 5 has a plugin architecture and doesn't have ad block built-in as shipped.
