These crash dumps represent a generic class of problem where communication has hung between Firefox and Flash.
There may have been a subtle change in timing hat's making this more prevalent on your machine, but the heart of the issue is a fundamental inefficiency related to the lack of native plug-in sandboxing on 32-bit Firefox. We retrofitted modern sandboxing to Firefox by bolting in a sandbox on our side of the interface, but it creates a multiple of the inter-process communication that would otherwise exist, and the result is that messages sometimes disappear or arrive in the wrong order.
Moving to the 64-bit version of Firefox generally resolves this, plus it delivers significantly better security through the virtue of using a sparse address space, and leave significantly more memory available to the browser. From what I've observed, even without Flash, it's much more stable than 32-bit Firefox on Win8 and higher.
