Flash Player Not responding

Hello,

I have been running into this issue continuously. Flash start not responding for no apparent reason (on Reddit, on Amazon, etc.) I've tried disabling hardware acceleration. I've tried switching browsers (I prefer Safari). I've tried uninstalling and re-installing flash. I have to go to task manager and force quit Safari and Flash Player. When it happens, it kills my CPU, using 99% in the activity monitor and effectively crippling the entire computer.

The solution I have found is to disable flash on all websites by selecting "Ask" in the plugin section of Safari's preferences. Then I only trust websites when they absolutely need flash to run (like HBOGO).

Is there any other solution to this? It's very frustrating.

Running newest flash version on OS X Yosemite 10.10.5. Using a 2014 Macbook Pro.
