Many people have updated to Firefox 3 since the Download Day 2008, which went so good actually, placing Firefox into the World Guinness Records.

You have may noticed many changes from the previous version, specially the address bar, and many people have asked me if the old tricks to speed your browser up are still working.
The answer is yes, and here you can find the most common tricks that are used by many people:
- Open Firefox, and type about:config in the address bar. Don’t worry about the warning that comes out.

- Use the filter above to find network.http.pipelining and set it to True by double clicking on it.
- Create a new boolean value named network.http.pipelining.firstrequest and set that to True, as well.
- Find network.http.pipelining.maxrequests, double click on it, and change its value to 8.
- Now look for network.http.proxy.pipelining and again set it to True.
- Create two new integers named nglayout.initialpaint.delay and content.notify.interval, setting them to 0.
Now restart your browser and check a few heavy-loading websites to see if those changes worked or not.

These items don’t appear in my about:config
network.http.pipelining.firstrequest
nglayout.initialpaint.delay
content.notify.interval
content.switch.threshold
content.interrupt.parsing
Do I just add them ?
The only two of those that I could find in my about:config were network.http.pipelining and network.http.pipelining.maxrequests.
content.switch.threshold is an integer. How do you set it to True?
Hey guys, I have checked your comments and updated the list.
If you create/change new values that really make improvements please let me know so that I can add them. Now I have tried all the ones listed and they all do their job on a 4Mbps line.
I had really slow firefox last few weeks… this speeded it up! Thanks for this
How will this work with using a dialup connection? Thanks.
This is really amazing, Thanks for the helpful post. At first when i was searching for it on firefox add-ons area i was disappointed about how to find something which can make my firefox faster, but now i’m happy – Thanks once again for the great help.

Hey guys thanks for the tips! I thought the parameter of about:config only works on firefox2 and older version but the show is still goes on! Someone told me about a new browser but its not Google Chrome, its called Maxthon, you can check at http://maxthon.com . they said it is the fastest browser on the net. can someone share us the magic in the box? thanks a lot. hope you guys can comment on my blog if you guys have the secret. have a nice day
i think he got these tweaks from http://www.helpero.com. under “how to” tab page 17.if its not in page 17, then try the other pages.you’ll find more firefox tweaks there, just like this one.^^
Perfect!! thanks for the tips
Thanks.. It doesn’t make it blindingly fast, but I do notice a difference. one question though, Is it normal for firefox’s cpu to be at 100 when loading pages?
How do you get it back to normal afterwards?
how do you “create a new boolean value”?
those configs ruined my firefox..now i have the error ” Scripts is running with a bad behavior” =(
These instructions are not very descriptive. Maybe you should try to explain it a bit more.
help please!! I tried part of this tweak and it made firefox slower and whilst trying to delete nglayout.initialpaint.delay it’s changed it to a ‘string’ instead of an integer. is this bad???
I really want to get it back to how it was. I have already had to have an HD replaced and can’t afford to do it again and am slightly scared.
On the other hand i really want to speed firefox up especially on initial start up as it’s painful. I want to avoid unistalling and reinatallin as i have so much save in my bookmarks etc
Please can someone help me?
many thanks

apologies had to correct my own spelling in the last message it should read ‘want to avoid uninstalling and REINSTALLING’ and ‘as i have so much SAVED in my bookmarks’!!
I was in a bit of a panic and rush to get some assistance!!
M
thankz bro…….really works
Make sure you follow these commands and it will work fine.
Also make sure that your registry cleaner doesn’t delete the new keys other wise it will go back to normal.
NOTE: These tweaks are for BROADBAND connections ONLY!
Yes, Firefox is already pretty damn fast but did you know that you can tweak it and improve the speed even more?
That’s the beauty of this program being open source.
Here’s what you do:
In the URL bar, type “about:config” and press enter. This will bring up the configuration “menu” where you can change the parameters of Firefox.
Note that these are what I’ve found to REALLY speed up my Firefox significantly – and these settings seem to be common among everybody else as well. But these settings are optimized for broadband connections – I mean with as much concurrent requests we’re going to open up with pipelining – You’d better have a big connection!
Double Click on the following settings and put in the numbers below – for the true / false booleans – they’ll change when you double click.
Code:
browser.tabs.showSingleWindowModePrefs – true
network.http.max-connections – 48
network.http.max-connections-per-server – 16
network.http.max-persistent-connections-per-proxy – 8
network.http.max-persistent-connections-per-server – 4
network.http.pipelining – true
network.http.pipelining.maxrequests – 100
network.http.proxy.pipelining – true
network.http.request.timeout – 300
One more thing… Right-click somewhere on that screen and add a 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. Since you’re broadband – it shouldn’t have to wait.
Now you should notice you’re loading pages MUCH faster now!
Thanks it was very helpful……..
Useless…I don’t see any diffrence – reverted back to default. I guess it’s better to invest in faster connection LOL
Thanks for this. I notice the difference right off the bat.
Thanks for this. I noticed the difference right away.
Thanks sir… Now its so fast to use the firefox 3.0.
Its very good trick.
for people who say they can’t find things READ FOR ONCE you just bloody add them -.-
how do u create the booleans i typed it in an then do what?
To reset your firefox
———————
1.Close all Firefox windows and tabs.
2.Open ‘Run’ from ‘Start Menu’
3.Type the following ‘firefox -profilemanager’ and hit ‘Enter’
4.Then a menu will be opened. Select “Create a new profile” will ultimately reset all your setting in Firefox.
( To undo this, Restart from 1 to 3 and select the default profile)
