I was a little bit confused of how can I configure Firefox with Firemin under Sandboxie supervision? So that I when I click Sandboxie then Firefox and Firemin will run together automatically. The actuall steps was that, I have to run the Firemin exe first then under its tab it has a tab to open up Firefox browser. Firemin is a separate program that works in effectively reducing firefox memory consumptions. http://download.cnet.com/Firemin/3000-18512_4-75454011.html Also any advice and suggestions for setting this program greatly appreciated.
