That's the socket that is used for communication with the X server. 
It's expected that an X app open it at least once.  Multiple times is a 
little odd, but in the case of firefox it's typical for things like the 
flash plugin to open their own display connections.  (So typical, in 
fact, that at this point the usual reason for an X server to hit the 
maximum client limit is the flash plugin losing its mind and eating all 
the connections.)
