I configured my webserver to show this. Just visit http://go/tzyrp .

This is a native dialog on Mac, and should probably stay that way..

Currently, it is native with --secondary-ui-md on Mac, but mac_views_browser runs:
 - toolkit-views selector
 - native viewer

which is weird (and a bug - I've made  Issue 766926 ).

Windows currently does this too, but I don't think it has a native OS *selector* - just a native viewer, which is used.

The "Select certificate" image (mac_views_browser_select.png) needs the 'close-x removed. The rest LGTM.
