How to Speed Up Firefox?Here is a great tip from shashank on how to make Firefox 10 times faster.

1. Type “about:config” into the address bar and hit enter. Scroll down and look for the following entries:

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 some number like 30. This means it will make 30 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.

  1. With due respect to you and your great blog the tweaks are “old as world” as we say in Poland. So calling them as a “great tips” is a lit of bit exaggeration. I suppose most of FF-users know them.

  2. You’re right.

    However, this blog is not for experienced users only, it’s for everyone :-)

    I thought that the setting for network.http.pipelining.maxrequests ranged from 1 -8. I read it at MozillaZine.

    I for one didn’t knew of this one.

    Mmmm saw it somewhere before but didn’t try it out… Should I ?

    @developar and everyone

    No you shouldn’t try it out. Enabling pipelining is known to lead to problems while surfing on some PCs. I’ve seen it myself (images stopped loading). That’s why it is not enabled by default.

    Actually, it doesn’t make much difference. I tried different settings for pipelining and found the default to be the best.

    Thanx Cody for the tip , any idea on how to speed up FF3 ?
    It’s lagging so much even when u have a fresh install !!!

  9. Hmm… I’m curious why you didn’t accept my last comment, what’s the problem? Send me an email please.

  10. What was the comment? System auto approves comment after your 1st one.

  11. Right. Ok so I wrote that @developar should try the settings, but if he wants really speed up FF, he should try Firetune. It can be downloaded from my website – where you can find lot of Firefox tweaks (polish website, but what for is GoogleTranslate ;)

    Thanx Skracanie , I’ll try it when I go home (using iPhone’s Safari now) :D

    You don’t need to set the pipelining max requests entry at any higher than ‘8’ as this is the maximum it will go see for more info.

    Hello ALL:

    How would you increase number of allowed WINDOWS and or number of allowed TABS in FireFox ? Is there also a linit by default for how many maximum tabs in each window or just total total of tabs in all open windows ?
