I'd add that after Firefox crashes. It's impossible to shut it down. I used to use Vista and the way I did it was to start Task Manager and force shut down Firefox. But now under WIn8.1, when Firefox crashes, I go to Crtl+Alt+Del. and can't start Task Manager anymore. It seems as though when FF crashes it brings down Task Manager along with it. It cannot be started, and hence I cannot force shut down FF.

That looks like hangs in the Shockwave Flash plugin.

You can check for problems with current Shockwave Flash plugin versions and try this:

• check for updates for your graphics drive drivers
  https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration
• disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
• disable hardware acceleration in the Flash plugin

I am already using the latest Nvidia update drivers. I will try to disable hardware acceleration in the Flash plugin and see how it goes before trying the second suggestion of disabling protected mode.

By the way, I have read about Shumway as a possible replacement for Abode Flash. Is it recommended to use that for Firefox?

Shumway is still being developed and hasn't been finished yet. It will only work with some basic Flash object and probably not with media players.
