When downloading Firefox, all of my saved PDF documents were changed into a Google Chrome document format, WHY? WHY isn't a person like myself warned before the downloading process begins so they have a chance to "proceed" or "abort" the download process? I want them all to be changed back to PDF, HOW do I do that?

Nothing happened to your files. Either the association for PDF files is messed up, or the icon cache is.

  1. Click the Windows logo orb on the taskbar and choose Default Programs.
  2. Click "Associate a file type or protocol with a program".
  3. Select .pdf from the list, then click the Change Program button.
  4. Choose the program you want to handle PDF files. Clicking PDF files in Windows Explorer or the desktop will then open them in that application.

To clear the icon cache, see the directions at

As far as I know, Firefox doesn't touch PDF files in any way. There's a proposal to associate Firefox with PDF files when they're not already associated with an application, but hasn't been implemented to date (bug 787674).
