* Set "network.http.pipelining.maxrequests" to a number like 30. This will allow it to make 30 requests at once. try playing with that setting, maybe 15 or 10, or maybe a higher 40 or 45? once again try at your own risk ect.
What are the risks and negatives to doing this? Can I do something similar on google chrome (I have FF too but I like chrome better so if it can be done on chrome I'd love it to be done there)?
An addon called Fasterfox used to do the same tweaks for Firefox 2, it didn't get updated for 3.x but I think it has had a member contributed fix to allow it to work with 3.x on Mozilla's addon site. Anyway from what I remembered when I was on Firefox 2, it did have some warning about which level of tweaking you'd chose, and the maximum warned about sites possibly banning you for the amount of connections you made to it, which is probably what the pipelining.maxrequests line does.
The maximum number of requests to pipeline is 8, any number higher than that should not make any difference. http://kb.mozillazine.org/Network.http.pipelining.maxrequests
