[Help] Bottom Firefox

I have a little problem here:

At the bottom of Firefox I have some weird bar (check attachment) that only appears on my own websites. Even at the most simple websites that are on my server, it still appears.. I never have it at any other website that is not hosted on my server. Is there any way I can remove that nasty bar?

Thanks.

After some tests I found out it only occurs with my forwarding domainnames. Any idea how I can remove it?

Your domain forwarding works via a frameset- this bar is simply the bottom border of the content frame.

That would be it, if you have a host get the DNS information.
