What i did was clicking on the green dot on the Disable column to turn it red so it was blocking Firefox.
The options you have in the program are to set Priority of the programs Low or High and to Disable a program.
The program increased my Call of Duty ping to 40 with high priority and 55-75 with low priority. My ping without the program is 25-30 so i unnistalled this piece of crap
I have 100Mbps internet so i can't really tell you how good the program is since...
