firefox speedups

I found these settings on slashdot for speeding up firefox 0.9:

Enter about:config into the title bar.

Set network.http.pipelining to True
Set network.http.pipelining.firstrequest to True
Set network.http.pipelining.maxrequests to 8 (I'm told higher values get ignored).
Finally and most important, set nglayout.initialpaint.delay to 0
