tapping the LJ oracle - Safari?

does anyone know of a firefox or other pc version of Safari? I need to test some web page compatibility and I don't have ready access to a mac to preview updates. ;-)
I searched the web for a while, and found several links to one site where you can preview a live url - unfortunately, the sites I am working on are not yet live. (oh, and the preview site didn't work, even on the live url I typed in to test)

thoughts?
do they make a version of Safari for pc?

thanks folks!
