When I down load a 'pdf' file from a specific secured web site and try to open it with Adobe Reader it gives me a pop-up stating "***.pdf is protected. Please enter a Document Open Password." Is Firefox creating these password protected files, if so; 1.) if I did have a password I lost it so would there be away I could recover it or 2.) is there some way I can prevent this password protection from happening. I have not had this happen on other web sites.

Thank you dan.mich
