Acrobat X and Adobe Reader X support viewing PDF files inside the Safari browser on Mac OS X. Acrobat X and Reader X do not support any other browser, such as Firefox or Opera.

Adobe PDFViewer for Mac OS X requires the following system requirements:
- Safari 4 for Mac OS X 10.5.8 and Mac OS X 10.6.4
- Safari 5 for Mac OS 10.6.4
- Acrobat and Reader via AdobePDFViewer Safari plug-in are 32/64-bit (64-bit available in Safari 10.6)
Note: If you don't have Acrobat or Reader, or haven't installed the PDFViewer plug-in, then Safari shows PDF files using the Mac OS X native PDF support. Support for many Adobe PDF workflows (such as the Collaboration feature or many Forms and Security features) is unavailable.
The AdobePDFViewer plug-in is used to display PDF files in Safari using Acrobat and Reader. This plug-in is installed as part of the Acrobat X or Reader X installation. The location of this plug-in is:
- To disable Safari integration, delete the AdobePDFViewer.plugin from /Library/Internet Plug-ins
- To reenable Safari integration, rerun the installer over the current installation. Start the Acrobat/Reader X installer from the original media, and then follow the onscreen prompts to complete the installation.
Uninstalling an older version of Acrobat or Reader after Acrobat X or Reader X has been installed removes the AdobePDFViewer plug-in
If Acrobat X or Reader X is installed alongside an older version of Acrobat or Reader, removing the older version removes the AdobePDFViewer plug-in.
To reenable Safari integration, rerun the installer over the current installation. Start the Acrobat/Reader X installer from the original media, and then follow the onscreen prompts to complete the installation.
Having multiple versions of Acrobat or Reader installed on the same system can cause plug-in conflicts. For example, suppose you have both Acrobat 9 and Acrobat X on your system and Acrobat 9 gets updated. In this case, the Acrobat 9 version of the AdobePDFViewer plug-in can overwrite the Acrobat X version of the plug-in. To correct the issue, follow these steps:
