Excellent, I could synchronize in my other ones PC the Add ons, simply install it in the first where you want them to be the other updated, do in this a synchronization first, only you have that you enter your email and Gmail's and every OK'S password.
After you make it in each PC and he will propose to you that you install every one of the Add ons in order that they remain the same.
