I recently started using linux and with it came iceweasel. I created a new email account and wanted to change the one i was using to sync iceweasel (firefox). So i removed the previes email, but when i entered the new email, i send the confirmation link to a wrong email. So should i be worried. I resend the confirmation link and entered a new password. But i'd like to know, what really happens when you make a mistake like this.

Thank You
