Now on the right browser, try a search with an author. The result will appear on the left browser. Click on the pdf link of the first article, then the second one, and then again on the first one (wait each time until the pdf file is open). When you click again on the first article, it should open almost immediately, because it opens from the local drive.

On the left browser, click on an author with the middle button. A new tab is created with a corresponding title.
