if you are using opera 22, there is no reason to keep using it, because it basically can,t do anything!!!, then you will try to install the chrome plug-in in the your 22, soon you will realize you better switch to chrome , on the other hand , if you are using 12, you don,t need a damn plug-in to satisfy your need , and you have the best interface among all browser!!!

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
