There are settings that limit the maximum number of connections, to protect the webserver, the proxyserver, the network and the webbrowser in itself. Similar settings have existed since Netscape 1.0. Even Internet Explorer has them. https://developer.mozilla.org/en/Mozilla_Networking_Preferences In your case, I think you're using a proxy server, since the network.http.max-persistent-connections-per-proxy is 8. You can see more settings (and change them), by typing about:config in the location bar, and filtering on network.http. The defaults ones in 3.5 have been enlarged compared to 3.0, if you compare them with the text above.
