Created attachment 467095 [details] Screenshot of the "This Connection is Not Private" screen, for visual reference. When I go a website that problematic certificate, I get a "This Connection is Not Private" page (screenshot attached), which is expected behavior. However, as a keyboard user, I cannot tab into the "view the certificate" or "visit this website" buttons after I click the "More info" button. I hope this can be fixed.

Investigating further, it looks like this issue is because the web page is marked up with <a> tags that don't have a proper href set. The easiest way to fix this issue is to have the href="#" and the onclick event have a return false.
