STR on Firefox 53.0a1 (2017-01-03) 1) go to https://prerender-test.appspot.com/ 2) type www.bbc.co.uk in the input field and press "prerender" button 3) wait for a short while, e.g. 5 seconds, click the http://www.bbc.co.uk link Actual result: It's navigated to the prerendered page www.bbc.co.uk, but the page wasn't loaded completely and the loading seemed stopped. Expected result: It's navigated to the redirect page www.bbc.com, and the page gets loaded completely eventually. Additional note: If in step 3, I open the www.bbc.co.uk link in a new tab, everything works as expected.
