The only extension i had was AdBlock, but it's been completely removed to try to figure this out.
But, I removed opuntrust.dat, restarted Opera and now Facebook works! I tried it on the work machine too and success there too. Yay!
I never would have thought to try that, because i don't know what it is. What exactly is this opuntrust.dat file?
Thanks so much everyone!

MAN!!! YOUR solution works GREAT, for the record, if anybody don,t know where exactly opuntrust.dat is, just search the hold c:, it won,t take long
