Hello I've had this problem in the past but it's never really affected a site I want to use before :p
Basically some sites have links or buttons, that when clicked on, do nothing. I notice this cannot be replicated using Chrome v5. I can give examples to one site (ffxivcore.com) however it requires registration to use these links.
My first thought was that these were badly coded sites, but this particular site admin is declaring Iron as an unknown browser and telling me to use Chrome.
Any ideas? Somebody else here must have experienced this, surely... I know this affects at least one other person on the site I listed.
