Within the last couple of days, all of my Adobe Reader files that have an extension of pdf have been changed to Firefox HTML files. When I attempt to open them, the HTML files are readable, but are not in pdf format. I cannot send these files to other people and they are not easy to print, manage, etc. Please tell me how I can change them back to pdf format.

Thank you.

Are that really HTML files with HTML markup code or some kind of text files ? What content is in the HTML files ? Is that the content what you would expect from the downloaded file ?
