An administrator needs to add the .xpi and .jar MIME types before the SmartHelp button can be installed on Firefox.
Users can install the toolbar button by accessing the following page from the Firefox browser:
http://<server>/<content_directory>/smarthelpsetup.html
When installation is complete, users must use the Restart Firefox button in the Add-ons dialog box or the button will not be configured properly. Users may then need to add the button to their toolbar with the Customize option.
To successfully install the SmartHelp button on Firefox, the location of the deployed content must be added to the addon exception list.
