Adobe Flash keeps crashing on ALL browsers on MAC

Adobe Flash has been killing me the past couple months. First I used google chrome and sometimes I would get an adobe flash crash, but as time went my adobe flash kept on crashing in which would slow down my computer to such a level I couldn't type anything on my computer for a solid 15 seconds to wait for my computer to respond, It was eating out my memory. I followed this by making sure there wasn't 2 flash players playing together in chrome, I looked up about:plugins on chrome to make sure. Everything was normal, and I still received crashes making my browsing experience terrible.

So I decide to use Firefox after hearing about how unstable chrome is, and I still receive the same flash player errors every time I use firefox.

Help.
