How To Disable PDF Browser Plugin For Firefox

Adobe Reader is an application that allows you to view and print PDF files. It includes a browser plugin for viewing PDF files directly in a web browser such as Firefox or Mozilla Suite. You can disable the Adobe Reader browser plugin and force .PDF links to open the associated program as an external helper application by using one of the methods below:

#1

1. Open the Adobe Reader program and go to the Edit -> Preferences dialog.
2. Select the Internet category and uncheck Display PDF in browser.
After closing Adobe Reader, open your Mozilla application’s installation directory, open the Plugins folder and ensure that the file nppdf32.dll is not present. If it is, remove it (or rename nppdf32.dll to Xnppdf32.dll). Failing to remove or rename this file may cause the browser to hang when attempting to open a PDF file.

Mozilla applications may use plugin scanning to locate the Acrobat Reader plugin. You can disable the plugin scan via about:config.

1. Open Firefox and type about:config in the address bar. Press Enter.

2. Type plugin.scan.Acrobat in the Filter box.

3. Double-click the option plugin.scan.Acrobat and change the value from 5.0 to 8.0. Press OK.

#2

Open your Firefox browser. Go to Tools -> Options menu and choose the appropriate option from the ones below:

Firefox 2

1. Go to Content --> File Types and click the Manage... button.
2. Select PDF from the list of extensions, click the Change Action button.
3. Change the action to Open them with the default application.

Firefox 1.5

1. Go to Downloads --> Download Actions and click the View&Edit Actions button.
2. Select PDF from the list of extensions, click the Change Action button.
3. Change the action to Open them with the default application.

Firefox 1.0.x

1. Go to Downloads and click the Plugins button.
2. Uncheck PDF from the list of extensions. Next time you click a .pdf file link in Firefox, you will get an Opening... dialog box asking what you would like to do with the .pdf file. Choose the option to open with the default application and check the box to do that automatically from now on.
