Just to clarify there was nothing wrong or different with our website. He had noscript enabled for GWT.
Yeah, I think my NoScript was the problem. It blocks all kinds of harmless stuff needed to view pages.
I had enabled it for Spidy, but when I went on Guild Wars Trade for some reason the bar that tells me it's blocking something must not have shown up right away. That or I suffered some temporary blindness.
Now that I've got it sorted Trade works beautifully on both Mozilla and Chrome.
I like the idea of rewarding something like tokens for armor for these group events in the open world. It means more choices for those of us not doing dungeons and if the tokens are account bound they can't be farmed by bots.
