I'm running many tests (on FF) one after the other and I would like each test to start off with a fresh browser (ie no cookies, no cache,..). One idea is to close the browser and open a fresh one for the new test (this will create a new profile and probably the cleanest environment possible).
This is causing too much trouble and taking too long so I'll give away some of the security of having a new profile for not closing the browser. How would you do such a thing? And is clearing the cookies enough?
