There are a lot of plug-ins (I mean not a browser plugin to view pdfs, but plugins of reader itself, e.g. for internet access, commenting a pdf, javascript in pdf, 3d in pdf and so on) pre installed with 'Adobe Reader X', almost 25. Some of them are annoying, some of them are unsafe to be enabled (e.g. Adobe Multimedia plug-ins allows PDF files to use built-in Flash, which is usually outdated and vulnerable in any version; ECMAScript may be vulnerable; Comments are annoying and never-will-use-it for me).

Open Adobe Reader or Adobe Acrobat. Open the Edit Preferences. Menu from the menu bar or use the keyboard shortcut Ctrl + K to get there even quicker. From the left pane, select Internet. In the Web Browser Options, uncheck the box next to Display PDF in browser. Choose the OK button to save and exit the settings window.

  1. Adobe Reader - Disable the Enhanced Security mode. To disable this option under Adobe Reader: Click on the Edit Menu Preferences Security (Enhanced). Uncheck 'Enable Enhanced Security'. Click on OK to validate. A few words of thanks would be greatly appreciated.
  2. Open Adobe Reader or Adobe Acrobat. Open the Edit Preferences. Menu from the menu bar or use the keyboard shortcut Ctrl + K to get there even quicker. From the left pane, select Internet.

Sep 14, 2015  How do I disable the Edge PDF Reader? - the one the opens a PDF file in a window that gives the user no option to enlarge or reduce or print or open with the Adobe reader, thus rendering it useless. All you get is a Save As option. I would like instead for it in invoke Adobe Reader. I do not have. If disabling Adobe Reader plugin manually did not solve your problem, then please try adding the following key in the registry editor and see if that helps. Open the Windows registry and go to HKEYCURRENTUSERSoftwareAdobeAcrobat ReaderDCOriginals 'bBrowserIntegration'=dword:00000000. Firefox has a built-in PDF viewer. We'll show you how to disable it and use another PDF viewer, like Adobe Reader, instead. Every time i click Disable then restart FF, it's back, running again. I do not want Acrobat, as i would rather use Foxit Reader. The only button in the Addons manager is Disable there does not seem to be a Uninstall or Delete this plugin option. Nor does adobe acrobat appear in Add/Remove Programs in Control panel.

I want to completely turn off some of Adobe Reader X plug-ins. Also, it would be perfect if this setting will be saved in case of Adobe Reader update with newer version.

PS Adobe Reader X = Adobe reader 10 (more exactly version 10.1); OS is Windows (any supported by AR X version)

Actually, an answer (Googled in 20 seconds):

Manage plug-ins

Plug-ins add more functionality, but they also increase the memory needed and security risks. To minimize memory requirements, you may want to install only the plug-ins that you use. To load a plug-in correctly, you must place it in the plug-ins folder. You can temporarily disable plug-ins when starting your software.

Disable a plug-in

  1. Do one of the following:

    • (Windows) Open the plug_ins folder (Program FilesAdobeAcrobat 9.0Acrobatplug_ins).
    • (Mac OS) Control-click the application icon, and choose Show Package Contents. Then double-click the Contents folder and open the Plug-ins folder.
    • (UNIX) Move the plug-in out of [location of install]/Adobe/Reader9.0/Reader/plug_ins.
  2. Select the plug-ins you do not want to load, and move them out of the folder. Some of the plug-ins may be in folders nested inside the plug-ins folder.

Disable all plug-ins temporarily

  • Press the Shift key immediately after starting Acrobat.

You can open PDFs on a web page either within your web browser or in Acrobat or Reader. Find instructions specific to each browser below.

Note:

Each browser has its own settings to control how PDFs open from a web page. Acrobat and Acrobat Reader do not include a preference setting to open web-based PDFs. To change the display behavior, follow the instructions below for your browser, or see the browser documentation on how to control plug-ins or add-ons.

  1. Open Internet Explorer, and choose Tools > Manage Add-ons.

  2. Under Add-on Types, select Toolbars and Extensions.

  3. Select All Add-ons from the Show menu in the Manage Add-ons dialog box.

  4. Note:

    If you do not see the Adobe PDF Reader add-on, try the other options on the menu. For example, on some systems, the add-on appears when you select Run Without Permission.

  5. Click the Enable or Disable button (it toggles depending on the status of the selected add-on):

    Enable sets the Adobe PDF Reader add-on to open PDFs in the browser.

    Disable turns off the add-on so it does not open PDFs in the browser.

    Select Adobe PDF Reader, and click the Enable/Disable button.

    For more information, see the Internet Explorer help topic Manage add-ons in Internet Explorer.

Microsoft Windows 10 will ship with two browsers: Internet Explorer 11 and the new Edge browser.

The Edge browser will be the default browser, and Internet Explorer 11 will be available to support legacy workflows. The new Edge browser will not have any support for ActiveX plug-ins. Therefore, the Acrobat/Reader plug-in won't work with Edge. For more information, see Change in support for Acrobat and Reader plug-ins in modern web browsers.

Use Internet Explorer 11 to open PDFs. To enable the Acrobat/Reader plug-in in Internet Explorer, see the steps in the previous section.

The Acrobat/Reader plug-in for Mozilla Firefox is based on Netscape Plug-In API (NPAPI), which is supported only till Firefox version 51. With Firefox version 52, support for NPAPI plug-ins is removed, and hence the current Acrobat/Reader plug-in will not work.

The Acrobat/Reader plug-in for Google Chrome is based on the Netscape Plug-In API (NPAPI) technology. Google announced that in April 2015 NPAPI plug-in support would be disabled by default in the Google Chrome web browser, with an override capability for advanced users. In September 2015, NPAPI support in the Google Chrome web browser was removed entirely.

For more information, see Change in support for Acrobat and Reader plug-ins in modern web browsers.

Note:

The Acrobat/Reader plug-in for Apple Safari is based on Netscape Plug-In API (NPAPI), which is supported only till Safari version 11. In Safari 12, support for NPAPI plug-ins is removed, and hence the current Acrobat/Reader plug-in will not work.

To view PDFs with Safari, you can do one of the following:

  • Set Safari preferences to use Adobe Reader plug-in
  • Disable AdobePDFViewer plug-in to use the default Safari PDF viewer

Set Safari preferences to use Adobe Reader plug-in to view PDFs

  1. In the Preferences window, choose Security and then click the Website Settings button for Internet plug-ins.

  2. Now select Adobe Reader in the list of plug-ins.

    Under the option When visiting other Websites, in the drop-down list, choose Allow Always and then click Done.

    Note: Facecam video game recorder free.

    This will set the browser to use the Adobe Reader plug-in to view PDFs.

Disable AdobePDFViewer plug-in to use the default Safari PDF viewer

You must have root user privileges to change Safari plug-ins. To display PDFs using the Safari PDF viewer, you must disable the Adobe PDF Viewer.

  1. Log in as the root user. The root user privileges aren't enabled by default because the root user can change system files. For more information and instructions, see one of the following Apple documents: Enabling and using the 'root' user in Mac OS X or OS X Mountain Lion: Enable and disable the root user.

  2. Type /Library in the Go to the Folder field, and click Go.

  3. Create a new folder in the Library folder, and name it Internet Plug-ins Disabled.

  4. Open the Internet Plug-ins folder, and move both the AdobePDFViewer.plugin and the AdobePDFViewerNPAPI.plugin into the new Internet Plug-ins Disabled folder.

    Note:

    If both AdobePDFViewer plug-ins are still in the Internet Plug-ins folder, drag them now to the trash. You may be asked for your name and password.

    For more information on disabling or removing plug-ins, see Apple Safari help.
