Multiple firefox

[Ruriko 0]

I want to run multiple firefox instances with each of them their own unique IP. How can I do this with AirVPN?

Spontaneous ideas:

1. Windows: Run Firefox with three different users, connect yourself three times to AirVPN using the proxy setting and configure the three instances to use those three different proxies. Unsure if it will work because one Firefox installation will use only one preference "bundle".
2. Use a VM with TOR. VM connects to AirVPN and runs a Firefox instance. A TOR instance (which too is Firefox) is running there, too. The host system is running a Firefox instance, too. So you basically use a TOR IP, an AirVPN IP and your real IP. Done.
3. Why the hell would someone want that??
