Hi As I am testing something on firefox browser at the moment i have a question. Is it possible for me to have more than one instance of firefox running on my computer with each having different settings. I would like to have eg. 3 browsers open with no 1 having A B and C extension installed - no 2 having D E and F extension installed and so on is that possible or can I do it in ohter ways so I can work in more firefox browsers at the same time?
