Now we need to clear up some confusion about Firemin. Firstly, Firemin uses a safe API function called EmptyWorkingSet that basically forces the process (in this case Firemin) to use less memory. Other words, tells Firefox to give back some of the system memory it’s hanging on to. For those of you who are a little more technically minded, you can read more about it here: EmptyWorkingSet function
. Using this function will sometimes result in a slight performance decrease measured in milliseconds , but I do mean slight, the chance of you noticing the performance decrease is almost zero.
