It's true that washingtonpost.com has a hell of a lot going on in the background (the newest verion of the NoScript Firefox extension on my PC even warns me about cross-scripting now). 90% of the time it eventually crashes my 770's opera browser. Man, I hate that site.
It's very rare (i.e. I've never seen it) to have websites actively trying to exploit your machine. If there's a URL which repeatedly and reproducibly crashes the browser, please raise it on http://bugs.maemo.org/ - otherwise there's no guarantee it'll be fixed.
Never assume the developers see the same bugs as you.
