How to install Adobe Flash Player mannuly for FireFox protable, when on a limted user acount

I have Firefox protable. Which is on my 1tb, and so i use it every where. I tryed to update Adobe Flash player on my main home computer, and it. Also on my Nanas computer, when i was there for a week, and i could play games on armor games, but, im here on another computer (Gradpas) and when i go to Armor games and play a game eg Dodge., it says i dont have the Adobe Flash. Due to being on a limited account, i cant ran the install program, and so i would like to know how to install Adobe Flash mannily. Thanks == This happened == Every time Firefox opened == Ever since i have used Firefox
