You can change the action for Portable Document Format (PDF) tom "Preview in Firefox" in "Firefox > Options/Preferences > Applications".

Set the pdfjs.disabled pref to false on the about:config page to enable the build-in PDF viewer.

The latest stable version of the built-in PDF viewer is available as an extension and this version can possibly perform better than the version shipped with the current Firefox release.
