XP SP2, Firefox 19.0.2 and all I get is a screen that quickly fades to black and then ... nothing.
I'm nostalgic too (not about Windows that said) but... Windows XP is the most exploited Windows right now: zombie botnets are made of a huge part of Windows XP PCs. Microsoft ain't patching several critical exploits on XP and it has been demonstrated for a fact that any local hole on XP means admin rights.
