Any idea what's wrong with my Safari?

[Centauri]

I'm getting really weirdly rendered web pages lately, but NBCnews is a prime example of which I've attached a screen shot. I've already uninstalled/update Flash, but it didn't seem to make a bit of difference. And of the several browsers I have installed, Safari is the only one giving me problems like this.

Any idears?

do you have any extensions installed? i started having issues with 'Helvetica the world', disabled it and problems went away

nbcnews.com rendered really strangely for me sometime in the past week. It looked like it pulled up the mobile site instead of the normal site (or something along those lines... clearly different page layout, or else the CSS was severely broken). Strange thing is, I was using Firefox. I refreshed and it looked normal again.

nbcnews looks fine to me. Do you use the adblock extension? My main issue with safari is underlined links
