Safari Woes

[TRDGT4Writer]

I've upgraded to a newish-used 2012 Mountain Lion-equipped Macbook Pro 15 because my old 2008 MBP15 went to a better home. I've the most weird Safari glitch I've ever encountered. It keeps crashing. I can't update it since I don't know what to update it to and the fact it won't let me.

I'm technical but I'm not engineering technical

I don't know how to stop it...

I've attached a PDF (you might want to magnify it after you download it)
