Alright,
Well I guess this is somewhat embarrassing, but here is what I discovered.
I rarely work out of windows desktop. Always have the browser and various tabs open, and just work out of the browser. I had occasion this afternoon to go to the desk top and low and behold, there was the task bar showing again. Go back to the browser and the task bar disappeared.
Restarted FF and the task bar is back in the browser.
Go back to the notifications settings and turn notifications off (again) and so far the task bar is still there...
And it appears the visual and audio notifications of what song is playing, and camera uploads is now gone.
The visual notification of a received email is gone, but I think the audio notification is still there. I'll have to test it some more, but my wife is tired of sending me 'test' emails this evening. :) There may be some settings relative to notification in outlook 2016 I need to look at for this.
Thanks again!
