Adobe does not yet maintain a plugin for viewing PDF files within Firefox for computers with Mac OS X. To view PDFs in Firefox:

• If you have a Mac with a PowerPC processor, the Schubert|it PDF Browser Plugin can be used to view PDF files in Firefox.
• If you have a Mac with an Intel processor, the Firefox PDF Plugin extension can be used to view PDF files in Firefox.

Only the first page is visible

If PDF documents open within Firefox but only the first page is viewable, make sure that the QuickTime plugin isn't set to handle PDF content:

1. From the Apple menu, choose System Preferences.
2. From the View menu, choose QuickTime.
3. Click the Plug-In tab and click MIME settings....
4. In the list of MIME types, click the triangle next to "Images - Still image files".
5. If "PDF Image" is checked, click the check box to clear it.
6. Click OK

The Adobe Reader plugin can be used to display PDF file inside the Firefox browser window. If there is a problem with the plugin, it may become impossible to do this. When you try to view a PDF, Firefox may try to download it instead.

For more information on the Adobe Reader plugin, see Using the Adobe Reader plugin with Firefox.
