Firefox will not use Foxit Reader plugin.


Why doesn't the configuration to use the Foxit Reader plugin for PDF files work? The Adobe Reader plugin (in Firefox) is used instead.

In Firefox 3.6.8 "Options" window, "Applications" tab, for "Content Type" -- "PDF file," the selected "Action" is "Use Foxit Reader Plugin for Mozilla (in Firefox)."

For "Content Type" -- "PDF file, in the "Action" dropdown list, no option is listed for "Use Adobe Acrobat (in Firefox)."

The "C:\Program Files\Mozilla Firefox\plugins" folder contains both (1) the Foxit Reader plugin (npFoxitReaderPlugin.dll ver., and (2) the Adobe Reader plugin (nppdf32.dll ver.

When Firefox connects to a website using a URL for a PDF file, the PDF document always appears in Firefox using Adobe Reader.

Given the configuration, why doesn't Firefox open the file using Foxit Reader? How can this be fixed?

Operating system is Windows XP Media Center Edition 2005.

Thank you.
