If I have understood correctly and you mean you want your font to look like the fonts on that screen grab, you might be in for a heck of a lot of tweaking.
Safari - I may be corrected on this - uses it's own redering engine for fonts, meaning that it can apply 'clearType' to any font - means that it blurs them slightly to make them clearer - sounds like a contradiction, but it works strangely. Windows itself has this feature, but even if switched on, I don't think effects web browsers fonts - again I may be corrected on that.
So, I'm afraid you're in for a lot of tweaking and trial and error. A personal fav is Myriad Web, font size 11px, a lot of other sites user Verdana 11px etc.
I'll be keeping a close eye on this one though because if there is a way to force clearType fonts onto browsers I'd love to know about it
Good Luck
