# Type "about:config" into the address bar and hit return. Scroll down and look for the following entries:
network.http.pipelining,
network.http.proxy.pipelining,
network.http.pipelining.maxrequests
# Normally the browser will make one request to a web page at a time. When you enable pipelining it will make several at once, which really speeds up page loading.
# Alter the entries as follows:
# Set "network.http.pipelining" to "true"
# Set "network.http.proxy.pipelining" to "true"
# Set "network.http.pipelining.maxrequests" to 8. This means it will make 8 requests at once. There is no point setting it higher then 8 as it is capped at 8 max. [The default value for this setting is 4]
# Lastly right-click anywhere and select New-> Integer. Name it "nglayout.initialpaint.delay" and set its value to "0". This value is the amount of time the browser waits before it acts on information it receives.
