Accessing Online PDF Content on a MacBookPro

Hello, I would appreciate some assistance with a problem that I am having accessing Online Material. I have a MacBookPro, running OSX 10.9.2. Many of the Websites that I access on a daily basis publish additional research articles as Webpages in PDF format. It is these Online PDF pages that I cannot easily access. When I click on the link, Safari opens a new Tab but seldom gives me access to the new Webpage. I can navigate to and interact with the Tab name. It will announce that it is selected. When I then try to navigate to the area of HTML content, I either cannot locate it or I just hear the word "Dimmed". This is the same whether I open the link in a new Window or a New Tab. The Work Around that I am using is to download the link and then read it with Preview. This is slow and unnecessarily cumbersome. So, what am I missing? Are there add-on's, extensions for Safari or a Mac App I should try? Any advice greatly appreciated. Sea No Evil. PS. I have tried using Google Chrome but, whilst that opens the PDF Webpage, I am invariably told that the "Page is Blank".
