Here is a screen shot of the preferences screen from Adobe Reader 11.0.2. By the way, the menu items to get there from inside of Adobe Reader is Edit Menu, then Preferences, and click on the Internet Category.
If you click the link "How to set up your browser to use Adobe products to view PDF documents" (red arrow in my picture), it will take you to the following webpage
On that webpage, you will see instructions on how to modify the setting that has been removed from Adobe Reader and Acrobat 11 from inside your specific browser. The browsers that they list help on are
• Internet Explorer 8 and 9
• Google Chrome
• Mozilla Firefox
• Apple Safari
Here is the text that appears at the top of the web page for reference
When you click a PDF link on a web page, it can open either within the web browser or directly in Acrobat or Reader. Each browser has its own settings to control how PDFs open from a web page. Acrobat XI and Reader XI 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.
So, as norwegian
has said, you do have to make the change from inside the browser. For IE 8 & 9, if you Enable
the browser plug-in, it turns on the option to display PDF's inside of the browser. If you disable
the browser plug-in, it turns off the option to display PDF's inside of the browser.
To me, this seems a bit more work and complicated for the end user. It was so easy before (just check a box inside the preferences of Adobe). Wonder why they changed this?
