Similar problems here. Aforementioned fixes only seem to do anything until I restart FF. When I hit the "Mark as Read" button I get this error "Session verification failed. Please try logging out and back in again, and then try again." Not sure if that's a not implemented again yet problem, or what, but I thought I'd mention it. Oh, and as mentioned before, the last post deal doesn't work, it just takes me to the first page of the thread. Cheers.
