FF will not open any pdf files with built in viewer or adobe. I have set applications in all different ways with no luck. PDF works with IE. I have ff 33.1.1 and Win 7 and i have tried all suggestions concerning pdf. I even downloaded ff again, uninstalled oldff, and installed new. no luck. all i get is a pop up stating ...download is in progress, please wait.... but it never loads. started after last update. Is ther a way to delete the last update to firefox?

thanks

Hello,

In order to change the default reader for PDF files (to not open PDF files with Firefox's internal PDF reader), follow these steps:

  1. Click the menu button New Fx Menu and click Options (Preferences for Linux and Mac).
  2. In the Options (Preferences for Linux and Mac) window, select the Applications panel.
  3. In the Search field, type PDF. You should find Portable Document Format (PDF).
  4. On the right hand side you should find an Action column. Use that to select your favorite PDF reader. In order to view PDF files in Firefox, choose Preview in Firefox.

did not work. i have tried all the different options under applications and none solve the problem. Does anyone know if an update can be removed from ff once it is installed? This started after las update.

Thanks
