I know that Firefox is working on the host computer because when I return to the host computer I can see everything. If Firefox is running when I connect to the host computer I can see Firefox, but when I move the mouse over a button and click on it nothing happens or so it appears on the remote computer. But when I return to the Host computer I can see that my clicks on items worked. Firefox just appears as a snapshot on the remote computer and will not change. If I close it on the remote computer it does close. But when I try to re-open Firefox all I see is a white screen. This only happens with Firefox. Chrome, Edge and Explorer all work just fine. Firefox version; 47.0.1 O/S Windows 10 - 64 bit. Thanks for any assistance.
