Firefox 3 beta 5 will have improved connection parallelism
Mozilla Firefox 3 beta 5 will, when it comes out, have some improvements in connection parallelism.
Just like IE8 increase from 2 concurrent connections per host to 6, Mozilla Firefox will also increase it to 6. The about:config entry for this is "network.http.max-persistent-connections-per-server".
Furthermore the max number of HTTP connections will be increase from 24 to 30. The about:config entry for this is "network.http.max-connections".
The number of HTTP connections that can be established per host will go up from 8 to 15. The about:config entry for this is "network.http.max-connections-per-server".
If you using Firefox from behind a proxy then the max number of concurrent connections will be increased from 4 to 8. The about:config entry for this is "network.http.max-persistent-connections-per-proxy".
All in all this will make Firefox 3 beta 5 even faster. These changes are needed since, according to Mozilla developers:
Sites are demanding more connections due to JS traffic, and we're using up more of the total connection limit with suggest requests, antimalware, extension traffic, etc.

For the technical people these are the new defaults:
pref("network.http.max-connections", 30);
pref("network.http.max-connections-per-server", 15);
pref("network.http.max-persistent-connections-per-server", 6);
pref("network.http.max-persistent-connections-per-proxy", 8);
Fasterfox which is a Add-on that has performance and network tweaks for Firefox uses these settings:
user_pref("network.http.max-connections", 40);
user_pref("network.http.max-connections-per-server", 16);
user_pref("network.http.max-persistent-connections-per-proxy", 12);
user_pref("network.http.max-persistent-connections-per-server", 6);
but these settings are not recommended since they, as Mike Shaver puts it, would get us (Firefox) banned from the internet.
