Frequent Flash Crashes

I’m running IceDragon on 64-bit Windows 7. I find that Flash frequently crashes, which is resolved only by closing and reopening the browser. I see the same behavior in vanilla chrome. I found an old topic but started a new one because the response didn’t seem very responsive to me. Does anyone have a checklist of things to look at or try to root cause these crashes? I know that such crashes are very common (I see others reporting them) and they may not be browser-related. I don’t think creating a new profile will have any effect on such crashes.
