Doesn't seem to work for me, except the first free example provided by the plugin itself. Registered my university emails, and tried to access articles from nature, Science and PRL, but all returned "PDF not found". Further test reveals that I need to connect to my university network environment via VPN to make it work outside the campus. Once VPN is stopped, the plugin stops working immediately. Well, if VPN is necessary, I don't see the point of using this plugin in, since PDF files are available via one-click anyway once you've located the article.
I am adding this in response to the developer response, which I appreciate very much. I followed the link https://kopernio.com/library-setup to try to set up for off-campus access. The first page says that I should NOT need to do anything unless I have trouble if my institutions are on their list. In fact, it is on the list. Then the next page explains how things work for off-campus without using VPN. Namely, one needs to use a proxy or Shibboleth authentication for the first time, and then the plugin will store the credentials for future uses. These are the routine methods one normally use, but self-storing the credentials and turning them on automatically when needed does sound saving some trouble. Nonetheless, what I am disappointed at is why I have to do this set-up while my institution is on the list. Anyway, I am gonna upgrade the star rating from 3 to 4.
