Adobe Flash Player Memory Hog on 2016 MacBook

I purchased the 2016 MacBook with the m7 chip.

I keep open mail, outlook, calendar and Safari. In Safari I have the following pinned tabs: philly.com; nytimes.com; macrumors.com; and teamsnap.com. When using Safari, I very often get the spinning beachball and when I check the activity monitor, it has Adobe Flash Player taking up 100% of memory. I tried uninstalling Adobe Flash Player and then reinstalling it. No luck. I then went to the genius bar where the genius told me that I was using a mobile processor and there was nothing they could recommend. Although, they told me that perhaps I shouldn't have the sites as pinned tabs.

Anyone else having problems with Flash on Safari using a MacBook (I don't care if its an m3, m5 or m7 processor). I found the genius response a bit callous. Safari is an Apple Application and pinned tabs was a feature in El Capitan (at least I think it was El Capitan if not Mavericks).

Any thoughts or help would be appreciated. I really like the machine, but find this frustrating.

Thanks in advance.
