You get tabs opening endlessly if you select the Firefox program to handle a file When you get an "Open with" dialog.

Sounds that the builtin Firefox PDF Viewer is disabled or otherwise isn't working. You can check the action for Portable Document Format (PDF) in "Options/Preferences application -> General: Applications" and make sure it is "Preview in Firefox".
Does this link open a blank PDF Viewer window?
