I don't mind the built in Firefox PDF viewer, but when I do view PDFs with it, it always chooses automatic zoom. I want it to always choose Fit Width. Is that possible to set up?

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. Go to Tools > Options (or Firefox > Options).
  2. In the Options window, select the Applications tab.
  3. In the Search field, type PDF. You should find Portable Document Format (PDF).
  4. On the right handside 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.

I understand that. i was saying I don't mind the built in reader, I just want to change the default zoom type to fit width instead of automatic on it.
