I need to open 4 Firefox "independent" sessions/instances in the same computer.
This is to the open the web-based WhatsApp GUI for 4 indepedendent business, with 4 independent phone numbers attended by the same agent. But we need them open all at the same time.
How can I do that?
PD: Firefox is our de-facto browser. Alternatively, if Firefox cannot do that, how can I do it in Chrome?
