When using firefox, I can no longer open attachments, pdf or downloads. A new window will open and it is blank. The only way to open an attachment or pdf is to shut down firefox and use safari. Everything works with safari so I can't understand what went wrong with firefox. I even download adobe reader thinking that would help. I then deleted my original firefox and re downloaded firefox again. It still doesn't work.

Try to disable the Adobe Reader plugin in Firefox (Tools > Add-ons > Plugins) and use the external Adobe Reader application or Preview application instead.

  • Firefox > Preferences > Applications > Adobe PDF document : Use Adobe Reader
