The naive method of downloading the papers is to find them through FIT library webpage. It is also possible to manipulate the paper's URL in order to get them from FIT. This Add-on does the manipulation by one click only.
In order to test this, google a non-free paper that is provided by FIT library (i.e papers in IEEE or ACM), and navigate to the paper's page. Then hit GetItFromFIT from your toolbar, and you'll automatically become re-directed to FIT and receive the paper in case you are logged into your university account.
