I'm with Anedg003, started using Chrome and have not gone back. Much faster than firefox and seems to be a little bit more stable. While you don't have all the extensions that firefox has, it does have some, they ones that I want anyhow.
I've gotten something like that once or twice, but usually when I was having connection issues.
I have NO issues with the forum now, or at other times.
Just out of curiosity, when was the last time you cleared your browser history?
