What this will do is limit the number of simultaneous connections to a single website Firefox will perform.

Simultaneous connections? HTTP is a connectionless protocol, so I am not sure what you mean. Could you elaborate? Thanks.

HTTP is not a connectionless protocol, meaning it must establish a connection before sending and receiving data - it does not broadcast data with no regards to its receipt.

It is, however, a stateless protocol, meaning connections are independent from any prior connection - persistent data must be re-sent and stored client- or server-side.
