In case anyone is curious...
- Safari and Chrome both use the same rendering engine, WebKit. Open source, and 100% standards-based.
- IE and Opera use their own, private, proprietary engines. Opera is a lot more standards-based than IE is (obviously).
- Firefox uses it's own privately-developed engine, but it is also open source. Not 100% standards-based, but pretty close. Firefox extensions are the only thing really keeping it in the game, though. There are a lot of people like myself, who would like to switch to something more compliant... but just can't give up things like AdBlocker. Every time I switch to another browser, I'm instantly reminded of just how ugly the internet really looks.
Edit: Also, why no love for Konqueror?
