How to speed up Mozilla Firefox

1. Type about:config into the address bar and hit enter. 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.

2. Alter the entries as follows:
Set network.http.pipelining to true.
Set network.http.proxy.pipelining to true.
Set network.http.pipelining.maxrequests to number 7.
This means it will make 7 requests at once.

3. 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.



and my Firefox went from fast loading to very close to instant loading on both frequently and never visited sites
nice one!
any chance of having a shell script that does those changes?
I recommended the nglayout.initialpaint.delay integer in another thread.

Thanks a lot for putting this together. I have been using these settings since 2006 and I never wait for any page to load.

You could also have spell check always enabled by changing the value of layout.spellcheckDefault to 2.

Thanks the pipelining settings are a lifesaver with facebook.
It does make a difference.
I also have a problem with tabs staying forever in the "loading" status even after most of the page is displayed (I have the tendency to open lots of tabs simultaneously)
I changed this:
network.http.keep-alive.timeout : 30
(or some other low value - default is 300)

I guess this more radical option:
network.http.keep-alive : false
could work too. I think this problem is due to some some kind of zombie connections.

PS: It works, i confirm. No more endlessly "loading" tabs.

And here are some memory-saving settings:
browser.sessionhistory.max_total_viewers : 0
config.trim_on_minimize : true
browser.cache.memory.enable : false
