I am having the desktop computer system which has the Windows XP OS and Mozilla Firefox is default browser. I have upgraded the Acrobat Reader 9 and when I am trying to open the PDF in the Firefox but I am not able to open PDF document. If you are having any ideas then reply me. Thanks in advanced.

Make following setting. It is fix your problem.

• Open Adobe Reader.

• At the top of the Adobe Reader window, click the Edit menu, and choose Preferences.

• In the left side of the Adobe Reader Preferences window, choose the Internet section.

• Check Display PDF in browser.

I am also suffering from this type browser issue and for that I have made some changes in the content type and its working so I think this will fix your problem.

1. Open the Mozilla

2. Click on Tools

3. Click on Options

4. Click on Application tab

5. Now see the content type and check whether PDF exist

6. If not then install the adobe again

7. If yes then check for the permission of the same.
