How to know which apps to shutdown when there is overheating? I once unfortunately closed a program that I found in the Activity Monitor to be using a lot of resources. A bit of Context: that day my macbook pro was suddenly heating up like crazy and the usually silent fan started blaring up! So I guessed that it was the root of all the trouble and force-quoted it, only to be subject to a screen of death notification!

So, in order to avoid this, I ask you to help me to be a better judge of the applications for situations as these!
The recent Firefox release (32) has a tendency to run in to conflict resulting in very high CPU consumption. That leads to high speed fans.

Mozilla has released a fix (32.01), but the results are yet to be seen.
