Here are three facts: 1) under Win 7 Pro or Server Standard I run simultaneously two FF tasks with 20 cores everyone without problems but not one task with 21 cores; 2) 21 copies and more of Far manager runs without problems also; 3) I can run simultaneously two task of Aimall program, each of them on 21 cores and more.
For this reason I assume that problem is in specificity of FF work. 21 cores on task are 21 copies of FF which run simultaneously. Probably for OS it is 21 users which want simultaneously to get access over network to FF?
