My Firefox would have been version 1.5 as I was using Fedora 6 and not Windows. I did install a Firefox update for Linux just yesterday so if there was a problem it may have been fixed by that. Anyway - an update....
I moved to a vps and have not had any problems to date. It looks like I probably was not overloading the server - I was just the biggest and easiest target to cool down their oversold server.
I may get up my courage soon to click on some more log file links and see if I can replicate the opening windows issue and will let you know if I manage to do so.
