When using my eprint function (e-mailing attachments to my printer through gmail), I have to send the attachment without subject or text in body to prevent it printing extra pages. Gmail automatically asks me "Send message without text in body?" and "Send message without a subject?" which was getting annoying. SO, I clicked the checkbox marked "Prevent this site from creating any more dialogs," hoping that would stop the pop-ups. Now, the pop-ups don't appear, but gmail simply doesn't send the message, so I get stuck unless I enter a subject and body text (which is a pain and wastes paper by printing an extra page). I can't figure out how to 'undo' what I did in either Firefox or Gmail. I'm using version 4.0.1. Help???
