Adobe Flash crashes as soon as I use it in Firefox

I am trying to use Adobe Flash to work in applications such as GoAnimate, but as soon as the editor loads, the plugin crashes. I will get the standard "The Flash Player plugin has crashed" message, which also says that there is no crash report. This issue occurs when I use other Flash applications. Some applications only cause Flash to hang, such as video players. Also, some lighter applications will let me use them for a while, and then they will, all of the sudden, crash, just right out of the blue. I have already tried starting Firefox in safe mode, and I still have the problem. I have also tried disabling hardware acceleration in Flash and Firefox, reinstalling Flash, reinstalling my graphics driver, and refreshing Firefox, all to no avail.

I have also noticed that when running GoAnimate (and other Flash applications), I get particularly high CPU usage. It is possible that my CPU might not be powerful enough to run certain Flash apps. Please let me know what you think about the issue, and what you think the cause of it might be.
