Can't create PDF file from Browser Window

Hi, I used to use Acrobat extensively (but not recently) to create PDF files from various websites. Today when I tried to do it from IE and from Chrome I found out that the ability to do that is no longer there.

I cannot figure out why it disappeared nor how to fix the problem.

Does anyone have any insight to this?

I'm using Arobat X, version 10.1.5.
