  * Test for Bug 1109146.
  * The tests opens a new tab and alt + clicks to download files
  * and confirms those files are on the download list.
  *
  * The difference between this and the test "browser_contentAreaClick.js" is that
  * the code path in e10s uses ContentClick.jsm instead of browser.js::contentAreaClick() util.
