how to load facebook using differnt proxys (software)

Hey,

I have a few facebook accounts but want to get some more and use clean ip's for each.

is there any browser or plugin for chrome that will let me switch ips easy and not lose the cookies and everything assigned to that proxy it (hope that makes sense)

Thanks
