Home Page Not Used When 'Open Firefox' With Cortana

Firefox 43.0.2 and Win 10 ... when use Cortana and speak
'Open Firefox', Firefox starts but does not open at the
defined Home Page ... instead starts at a Google search
with a search argument of "Open Firefox".

BTW: Firefox is defined to be the default browser and
after FF starts the Home Page can be accessed by clicking
the 'Home page icon'.

When FF is started without using Cortana, the Home page is displayed.

I think Cortana can only open Universal Apps.

Thanks for the update
Not sure about Universal Apps ... but Cortana DOES open Firefox ... just doesn't 'go to' the defined Home Page.
