When accessing PDF files on the Web, you have two options: opening the PDF file within the browser window, or opening the PDF file in Acrobat Reader® as a separate application. The following instructions will help you configure Netscape Navigator™ and Microsoft Internet Explorer® for Windows 95, Windows 98, Windows 2000, and Windows NT 4.0 to use Acrobat Reader in one of these ways.

Some Acrobat Capabilities Don't Work in
Netscape 6.x Browsers

Adobe Acrobat 4.0 and later, Adobe Acrobat Reader 4.0 and later, and Adobe Acrobat Business Tools 4.0x install a plug-in that enables you to view, navigate, and print PDF files and to fill in PDF forms from within Netscape 4.x browsers. This plug-in (nppdf32.dll in Windows, PDFViewer in Mac OS) is not fully compatible with Netscape 6.x browsers; when using this plug-in, Netscape 6.x browsers do not support the following: -- Fast Web View (byte serving or page-at-a-time downloading). With Fast Web View, PDF files download page by page and appear quickly over slower modem connections. In a Netscape 6.x browser, you must download an entire PDF file before you can view any of its pages. -- PDF forms. You cannot post PDF forms that you complete in Netscape 6.x browsers to a server; if a PDF form has a Submit button, you cannot submit the PDF form from within the browser. -- Choosing File > Print to print a PDF file from the browser. Instead, you must use the print icon on the Acrobat toolbar. Adobe will continue to communicate to Netscape the seriousness of these issues for Adobe's customers. Adobe encourages you to contact Netscape as well.

Configuring Netscape 4.x

You can configure Netscape for Windows to use Acrobat Reader as a browser plug-in or as a helper application. When Reader is configured as a plug-in, the PDF file displays within the browser window. When Reader is configured as a helper application, the PDF file displays in a separate Reader window.

Configuring Netscape 4.x to use the Acrobat Reader plug-in
The Acrobat Reader installer configures Reader as a browser plug-in by default. When you install Acrobat Reader, the installer places the nppdf32.dll plug-in in Netscape's plug-ins folder at:

c:\Program Files\Netscape\Communicator\Program\Plugins

No other action is needed. After restarting Netscape, clicking a PDF file link in a Web page opens the file in an Acrobat Reader window within Netscape's browser window. All the toolbars and controls available in Reader as a stand-alone application are available when using the browser plug-in.

Configuring Netscape 4.x to use Acrobat Reader as a helper application
If you don't want PDFs to open in your browser window, you can set up Reader as a helper application. When you use this configuration and click a PDF file link in a Web page, Netscape opens Acrobat Reader as a separate application where you view the PDF. To configure Netscape to use Acrobat Reader as a helper application:

1.   In Netscape, choose Edit > Preferences to display the Preferences dialog box.
 
2.   Select Applications in the Navigator category of the Category list:
Select Applications
3.   Click New Type.
 
4.   In the New Type dialog box, do the following:

  a.   Type Portable Document Format in the Description of Type text box.
 
  b.   Type pdf in the File Extension text box.
 
  c.   Type application/pdf in the MIME Type text box.
New Type Window
  a.   Click Browse, locate and select the Acrobat Reader 4.0x application file,
Select Acrobar Reader
      and then click Open. The path to the Acrobat Reader 4.0x application file displays in Application to Use text box.

5.   Click OK to close the New Type dialog box, and then click OK to close the Preferences dialog box.
 
6.   Restart Navigator.

Once Reader is set up as a helper application, you can switch between using Reader as a helper application and using the browser plug-in by selecting and deselecting Web Browser Integration in the Options area of the General Preferences dialog box in Acrobat Reader 4.0x.
