I was not ware that safari was available on PC. While Firefox is not perfect, it's the best available, (for non-hackers).
I might recommend (again) an investment of an hour or two into replacing windows, as that is the source of your woes. Ubuntu is a good place to start. (so is any other open source linux OS just google "free operating systems" )
One good thing about them, like Firefox, they are free, and NOT made my microsloth.
