I think so. Slim Jim over at cbradioforum posted this some time back and it just got pinned to keep it on top.
I tried it and highly recommend it if you like FireFox.
Open Firefox browser
In the address bar at the top, type in about:config
in the new window that opens, in the address bar where is says filter, type in network
Now look for these, they sit on top of each other
network.http.pipelining double click on this and it will change to "true"
right below is network.http.pipelining.maxrequests double click this and change the value to 150
now close out Firefox and reopen it
Faster Firefox
