Actually, this is not your problem.
Web pages that don't display in a normal web browser suck. There is really no excuse for that.
It is beyond me why so many people have to be so darn ignorant and don't want to understand that not everybody has JavaScript, cookies, WebBugs, and all those other nasties enabled.
I can understand if someone can't be bothered to provide a 100% good layout for every browser in existence, but you should at least be able to see *something* in every browser, in particular in Firefox...
Speaking of nasty stuff... did you notice that sourceforge does not allow you to log in if you have privoxy enabled? Did you ever wonder what the cookies and requests going to google-analytics.com do?
