Fix for Opening Salesforce PDFs (like the Release Notes)

Knowledge Article Number 000176783

If you’re having trouble opening or viewing Salesforce PDFs (like our Release Notes), refer to the following troubleshooting information for your browser. The issues we’ve seen are browser-related and not a problem with the link or with the PDF.


Internet Explorer

Some customers  have reported issues opening PDFs using Internet Explorer. We’ve been able to replicate this problem on IE 8 (with Adobe Reader X), and one workaround is to disable the “allow fast web view” option in Adobe Reader.


To disable this option:

  1. Open Adobe Reader.

  2. Select Edit > Preferences.

  3. Select Internet in the left-hand column.

  4. De-select Allow fast web view and click OK.


If you’re still unable to open PDFs from the web, try uninstalling Acrobat Reader and installing the latest version here. Or you can right-click on the PDF link and select to download the file.



The new version of Firefox includes a new built-in PDF viewer that degrades the appearance of text (especially when zooming in).


One workaround is to disable this plug-in so you view PDFs in your native Adobe PDF reader. To disable the built-in viewer:

  1. At the top of the Firefox window, click on the Firefox button and then select Options

  2. Select the Applications panel.

  3. From the content type list, select Portable Document Format (PDF).

  4. Click the drop-down arrow in the Action column for the above entry, and select Use PDF reader name (in Firefox). Click OK.
