I am trying to speed up firefox as I have always done so in previous firefox versions as stated in this website How To Speed Up Firefox (Helpful Vanity)"http://www.freerepublic.com/focus/news/1299854/posts
In firefox version 3.5 and 3.6 following the instructions stated in the website EVERY setting that I change except network.http.pipelining.maxrequests" to some number like 30 does not save. It returns to its original number. Why do all the other setting when i change them save and the network.http.pipelining.maxrequests returns back to its normal state.Tweaking using the 'network.http.pipelining.maxrequests', is allowing more multiple requests to be sent before any responses are received. This speed tweak of boosting it to 30, give the effect of more speed loading multiple websites on a broadband connection. However, in fact you are pretty much just DDOSing and lossing half of these connection anyway (if your connection or the servers can't keep up). Some websites hate it, Firefox might of caught on and limited it down to 8.

Possible values and their effects
Any integer from 1 to 8 INCLUSIVE determines the maximum number of requests to pipeline at once. A value of 1 disables pipelining. (Default: 4)

'network.http.pipelining' or 'network.http.proxy.pipelining' (depending on whether you use a proxy) must be set to true for this preference to take effect.

Higher values will cause a DELAY before the first request completes but will make the last request complete sooner. Higher values will also cause more of a delay if a connection fails.

Has an effect in:
Netscape (all versions since 6.1)
Mozilla Suite (all versions since 0.9)
Mozilla Phoenix (all versions)
Mozilla Firebird (all versions)
Mozilla Firefox (all versions)
SeaMonkey (all versions)
Camino (all versions)
Minimo (all versions)
I think 8 or 10 was like the recommended maximum to go to.
