nah.. I was at first, but I guess there's no point in trying to explain it. It was just a suggestion to explain the issue that I have witnessed many times, mostly on Opera, on many different workstations accessing many different web sites with user log ons. The new Firefox does appear to be different with the caching than I remember during the beta phase. I also noticed that you can import IE settings into Firefox so if you've turned off caching in IE to begin with, which most web developers do, then it may explain why you've never witnessed it.
Uh, whatever FF was doing or not doing, the Forum and FF have made peace and I am able to log off and the logon icon comes up with a blank username box. I didn't do anything in particular, I quess shutting the computer down for a few days cleared memory enough to get stuff clear. Whatever...
