This may happen after you have upgraded into a new Microsoft Office Suite.

Cause

The Firefox file extension may be corrupted.

Resolutions

To resolve this problem,

  1. In your Firefox Browser, choose Tools > Add-ons > WebDAV Launcher > Options. This will bring up a pop up window, with a list of office extensions and the file handler. Delete each of them if you are using Microsoft Office.
    OR
  2. Delete Firefox's own file extension. Refer to Mozilla's documentation.
