Hello. If downloaded file has ".pdf" extension firefox can't open it saying "file.pdf could not be opened, because the associated helper application does not exist. Change the association in your preferences." It opens pdfs only after removing ".pdf" from filename (it works for all of pdf documents). I have 2 pdf related options in Preferences->applications: Portable Document Format (PDF) - is set to preview in firefox; PDF Document - is set to Use (default) and it has not option preview in firefox. I'm using arch linux and xfce4. There is MIME Type settings in xfce4 & it is set to open in firefox: "application/pdf" - "Firefox". Thanks
