Is there some way to have multiple unique instances of the same browser running at the same time? By that, I mean cookies and stuff don't transfer over to each separate instance of the internet browser. I'm doing a project, and I'm creating multiple facebook accounts for it. The only problem is it is a hassle to log into the difference accounts each time, and I was hoping there is some work around for that. I realize I could just download multiple different web browsers, but there must be some way to use it with one browser.
