What is the status of this?

Unfixed until someone finds the time. I fixed most of the calls by providing a triggeringprincipal and adding parameters to the tabbrowser but there are still some bad ones around.

about:plugins is as good as dead but there is still about:performance about:memory and about:serviceworkers. Maybe a few others too.

openNewWindowWith() and a few other functions need to be extended with triggering principals.

Bug 1589189 takes care of this problem here too. Already working in the unofficial 2.53.1 builds.
