I just installed portable version of TOR Bundle with IM Now my doubts are : How do I change my IP when ever I need Like I need to change 10 IPs. So how do I change. Should I disconnect and re connect tor? So I already run a firefox open with 100s of tabs and cookies. So this TOR portable firefox, should I open from the PC or should I close the exisiting firefox and open? Can I run both together which I open social network accounts. So this new TOR does not open the old cookies ri8? So the old cookies in firefox has no problems. No need to clear it ri8? Please clear these small doubts so that I can start using it!
