Minimize, maximize and close buttons do not work. Also I can not select from a drop down menu unless I scroll with a cursor and hit enter
this all started when I upgraded to 50.0.2 Also if I click on about Mozilla Firefox I can not close the window that comes up.

I can close Firefox from the task bar but not the buttons on the top right. Thunderbird is the same problem. Chrome works fine so it has to be a Mozilla problem.

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options) key, and then starting Firefox.
A small dialog should appear. Click Start In Safe Mode (not Refresh).
Is the problem still there?
It still does not work. Immediately upon opening Firefox the problem does not exist. As soon as I open a web site the minimize, maximize and close buttons do not work. Also I still can not select a things on a pull down menu.
Any website?
Start your Computer in safe mode with networking. Then start Firefox. Try Safe websites. Is the problem still there?
