I booted Knoppix, and again I had the same problems. Firefox opens a "checking compatibility of add ons" window for several minutes, then this disappears, then several minutes later the FF browser pops up. From here I disabled IPv6 again, closed and re opened FF. I tried to access the knoppix website first and that didn't work, so I typed in 72.232.180.133 again, and it worked! Brought me right to the Knoppix site, and I made note of the google adds that showed up on the side. After that I could access any site freely, so here I am. So I guess the same procedure did yield the same result which is rather interesting. But since it takes ten minutes from when knoppix loads to when I can access the net, I am trying my luck with a persistent disk image saved to a USB drive.
