How do i log into multiple gaia account at once?

I want to know how to log onto multiple gaia accounts on one computer at a time. It needs to work with Mozilla firefox. I've tried turning off cookies but it won't let me log onto any of them if I do that.

You'd need to use two different web browsers. So, the answer to your question is - you can't, with just firefox, b/c they both read cookies from the same place.

And, if this is an attempt to game gaia, it won't work. Trust us. Every time somebody posts here saying they tried it, or it worked, etc, it was a scam.
