Hi Since I upgraded to FC5, Firefox has slowed significantly on all accesses. I remember having the same problem on FC4 and someone suggested that I turn off Firefox's use of ip6, which worked, but I didn't write down the instructions. Could someone tell me how to stop Firefox from trying to use ip6. I'll write them down this time.
