The Acrobat/Acrobat Reader plug-in for web browsers relies on the cross-platform plug-in architecture NPAPI, which had been supported by all major web browsers for over a decade. The following browsers have dropped support for NPAPI, and therefore Acrobat/Acrobat Reader plug-in does not work on these browsers anymore to display the PDF.
- Mozilla Firefox (v52 and above)
- Google Chrome (September 2015 release onwards)
- Apple Safari (v12 and above)
- Microsoft Edge
For more information, see Change in support for Acrobat and Reader plug-ins in modern web browsers.
Internet Explorer
Internet Explorer 11 uses an ActiveX based plug-in. Follow the steps below to configure Internet Explorer to use the Acrobat/Acrobat Reader plugin for viewing PDFs:
-
-
Under Add-on Types, select Toolbars and Extensions.
-
In the Show menu, select All Add-ons.
-
In the list of add-ons, select Adobe PDF Reader.
Pastaba: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.
-
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.
For more information, see the Internet Explorer help topic Manage add-ons in Internet Explorer.
