Note: In this document, the term "Acrobat" refers to any of the following Acrobat products: Adobe Acrobat, Adobe Acrobat Reader, Adobe Acrobat Approval, and Adobe Acrobat Business Tools; the term "Netscape browser" refers to Netscape Navigator 4.x or Netscape Communicator 4.x.

You can display PDF files within a Netscape browser by using the Adobe Acrobat PDFViewer plug-in or by using Adobe Acrobat as a helper application. When you use the PDFViewer plug-in, the Netscape browser displays PDF files within its window. When the Netscape browser uses Acrobat as a helper application, PDF files appear in the Acrobat window outside the browser window.

Using the PDFViewer Plug-In
When you install Acrobat on a computer that has a Netscape browser installed, the Acrobat installer places the PDFViewer plug-in file into the Adobe Acrobat [version]: Web Browser Plug-in folder. You need to move the PDFViewer plug-in file from this folder into the Netscape Navigator: Plug-ins or Netscape Communicator: Plug-ins folder.

If you select a PDF file in the browser while the plug-in is installed, the file downloads to the browser's Temp folder, and the browser uses Acrobat to display the file within the browser window.

If a PDF file you select doesn't appear within the browser window, do one or more of the following:
-- Make sure that the PDFViewer plug-in is in the Netscape Navigator: Plug-ins folder or the Netscape Communicator: Plug-ins folder. If it isn't, copy it into that folder from the Adobe Acrobat: Web Browser Plug-in folder.
-- Deselect Acrobat as a helper application:
1. Open the Netscape browser, and choose Edit > Preferences.
2. Click Applications in the Category scroll list.
3. Select Application/pdf, Portable Document Format, or Reader from the Description list or the Handled By list.
4. Click Delete.
5. Repeat steps 3-4 for each reference to Acrobat or PDF files.
6. Click OK to close the Preferences dialog box, and then restart the Netscape browser.

Using Acrobat as a Helper Application
When you configure the Netscape browser to use Acrobat as a helper application, the browser starts Acrobat, and then displays PDF files in the Acrobat window.

To configure the Netscape browser to use Acrobat as a helper application:
1. If the PDFViewer plug-in is installed, quit the Netscape browser and remove the PDFViewer plug-in from the Netscape Navigator: Plug-ins folder or the Netscape Communicator: Plug-ins folder.
2. Start the Netscape browser.
3. Choose Edit > Preferences.
4. Click Applications in the Category scroll list.
5. Do either of the following:
-- If Portable Document Format is listed in the Description section, select it, click Edit, and then go to step 9.
-- If Portable Document Format isn't listed, click New, and then go to step 6.
6. Type Portable Document Format in the Description text box.
7. Type application/pdf in the MIME Type text box.
8. Type pdf in the Suffixes text box.
9. Select Application in the Handled By section.
10. Click Choose.
11. Locate and select the Acrobat application file, and click Open.
12. Choose PDF from the File Type pop-up menu, and click OK.
13. Restart the Netscape browser.
