i'm using form_auto. When I receive new data for my form, I can delete it, click (i) to view information. But clicking on the pencil to edit it will give me this error

The page isn't redirecting properly

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.
This only happens on my live site. And only with firefox...... With IE I can edit the form no problem. My local machine installation has no problem

Any idea how I can fix this? Cache? Firefox settings?
