Many factors can affect the display of a document in PDF format on the web. This problem can appear as:

Adobe bundles the Acrobat Chrome extension with Adobe Acrobat Reader DC so that you can easily open PDFs in Reader while browsing the web. Once installed and enabled, the extension will: Open PDF files in the Acrobat Reader desktop app. Offer a consistent and reliable PDF viewing experience. Adobe Flash Player 30.0.0.134 (Plug-In)+(Active-X)+(PPAPI): Released on July 10, 2018. Use only if you really need it. Use only if you really need it.

• A blank (or gray) page in the web browser
• PDF files open and then immediately close
• PDF files download instead of display in the browser
• 'Adobe Reader blocked for this website' message (especially in Safari 7+)
• A broken object link (for example, a red square, a blue triangle, or a blue circle)

• Internet Explorer error: such as 'Internet Explorer has stopped working...', or 'Microsoft Visual C++ Runtime Error...'

Some of the causes for PDF display problems in an Internet browser include:

• Browser plug-ins are blocked (unless set as 'trusted')

• Corrupted PDF or related temporary files

• Corrupted browser upgrade or add-on program

• Restrictive security (or 'sandboxing'), pop-up blocker, or cookie settings

• The web browser isn't configured to display PDF files properly

• The web browser isn't configured correctly with the Adobe PDF Browser plug-in

• Out-dated, incomplete or conflicting versions of Adobe Reader (or other PDF Reader)

• Incompatible web browser settings

• The web server on which the PDF file is stored can't deliver the PDF file

Restore Browser Settings

To restore the default tabbed browsing settings that control how pop-ups and links from other programs are displayed in Internet Explorer:

1. Close all browser screens and try again.
2. In Internet Explorer's browser menu, select Tools (or the gear icon), and then Internet Options.
3. In the Tabs section, click the Tabs button in IE 10 and 11 (Settings button in IE 9 and earlier).
4. On the Tabbed Browsing Settings screen, click the 'Restore Defaults' button.
5. Under 'When a pop-up is encountered', select 'Always open Pop-ups in a new window.'
6. Click OK and try again.

Reset Internet Explorer (11, 10, 9, 8 or 7)

Internet Explorer may fail to function properly after being upgraded, after free browser add-ons (such as animations, extra search toolbars, dictionary/translator/thesaurus, pop-up blocker, weather/stock tracker, etc) have been installed, after installing (or uninstalling) a different browser (such as Google Chrome), or after running a 'registry cleaner' or similar program. Free registry cleans are risky because they can delete important files.

While they sound useful, free browser add-ons can hijack or block the browser's normal links so they can direct you to ad supported links (like most freeware). You may need to uninstall the offending free add-ons and free toolbars (such as Ask.com, Crawler, InfoAtoms, FunWebProducts, MyWebSearch, MySearch, My Way Speedbar, Search Assistant) or desktop gadget adware (such as WeatherBug or WhenU) to allow linked documents to display properly.

If a browser error such as 'Internet Explorer has stopped working...' is displayed, you may need to reset Internet Explorer.

To reset Internet Explorer back to its original default settings (see warning note below) you can either click here to run the Microsoft's 'Fix it' utility, or you can follow the instructions below:

1. Start Internet Explorer (if possible) and select the Tools menu. If Internet Explorer fails, open the Windows Control Panel.
2. Click on Internet Options
3. Select the Advanced tab
4. Click the Reset button
5. In the 'Reset Internet Explorer Settings' dialog box, click Reset to confirm.
6. You may need to re-start Windows for all changes to take effect.

For details, see Microsoft's article 'How to reset Internet Explorer settings'.

Warning Note.

• This Reset disables all Internet Explorer temporary files, disables all browser add-ons, and resets all changed IE settings back to their original default. Resetting Internet Explorer to its default settings does not delete your favorites, feeds, Web Slices, and a few other personalized settings. However, when you delete personal settings, some web pages that rely on previously stored cookies, form data, passwords, or previously installed browser add-ons might not work correctly.
• Resetting Internet Explorer's settings is not reversible. After a reset, all previous settings are lost and cannot be recovered.
• Before resetting everything, you might first want to either reset specific settings, or delete just your browsing history (as described previously). If neither of these resolve the problem, then completely reset your browser.

Safari 5.1 Workarounds (per Adobe)

Adobe Reader plug-in and Acrobat plug-in versions before 10.1.3 are not compatible with the Safari 5.1 browser included with Mac OS X 10.7 and 10.6. The Adobe Reader and Acrobat standalone applications are unaffected and Safari 5.1 renders PDF documents natively. However, the Adobe Reader and Acrobat browser plug-ins will not function properly for document links that require either plug-in to render PDF documents in Safari 5.1.

Options include the following:

• Continue to use Safari 5.0.x and Mac OS X 10.6.
• Download and run Firefox to use Adobe X (10.3.1+).
• Save the PDF file from Safari to the computer, and then open it directly in Adobe Reader or Acrobat.

For more information and possible updates, see Apple Safari 5.1 and Adobe Reader/Acrobat Advisory.

Safari 5.0.x

The AdobePDFViewer plug-in used by Acrobat and Reader to display PDF files in Safari (5.0 and earlier) on a Mac is installed in

/Library/Internet Plug-ins/AdobePDFViewer.plugin .

To disable/remove the Adobe plug-in in Safari on a Mac, close Safari, use the Finder to go to the Internet Plug-ins Library, and drag the AdobePDFViewer.plugin file to the Trash. To save the plug-in for possible use later, you can create a folder called 'Disabled Plug-ins' in your home directory, and then drag this file to that folder. Then, to reinstall the plug-in, just drag the file back to its original location. Otherwise, to re-install the Adobe plug-in, re-install Adobe Reader or Acrobat over the current installation.

After you remove a plug-in by moving it to the Trash or another folder, you must restart Safari for the change to take effect.

Verify or Reset the 'Display PDF in Browser' Preference

To ensure that Adobe Reader or Acrobat are set to display PDF files in your browser:

1. Open a PDF document window in your browser. (It doesn't matter if the document itself is displayed. However, you can paste the URL path to a PDF document in your browser's address bar if the link to the document fails to automatically open the document.)
2. Right-click anywhere inside the document window and select 'Page Display Preferences'
3. In the Categories list on the left pane, select Internet
4. Check 'Display PDF in browser'
   • If 'Display PDF in browser' was already checked, reset it by
     • Uncheck it and click OK
     • Repeat steps 2 and 3 above to re-open the Internet Preferences screen
     • Check 'Display PDF in browser' again and click OK
5. Click OK to close the Page Display Preferences screen.

View PDF in a 32-bit version of Internet Explorer

Acrobat and Reader are 32-bit applications on Windows. If you try to open a PDF in a 64-bit version of Internet Explorer, the PDF opens in stand-alone Acrobat or Reader, not in Internet Explorer.

Mac Chrome Adobe Reader Plugin
