Optimizing Firefox 3 Hacks And Tweaks

Updated on March 21, 2012


Previously I was using Firefox 2 and was happy with its performance. Then I downloaded the latest version on world download day. More than 60 million downloads are done till now. Earlier I used to tweak my browser to optimize it for the best performance. Now I am experimenting with the possibilities of the latest version. I am sharing them with you here. However I am a little disappointed with the extension compatibilities of the latest version. I guess I will need to re-install most of the extensions I was using with the earlier version. Its a pain considering the fact that most of those extensions do not have an updated versions for Firefox 3. I also found out what more I can do with the latest firefox, and then thensome easter eggs too! I hope these tips, tricks, hacks and tweaks will help you in optimizing the browser to suit your needs.

Optimize Firefox 3

As I was trying to tweak Firefox 3 to suit my needs, I realized that it is more cutomizable and user friendly than the previous version. I used the 'about:config' to do most of the tweaks. If you want to them please take a back up of your settings first, so that you can revert back, if you don't find the hacks and tweaks useful for you.

Firefox 3 Hacks And Tweaks

The following tweaks are obtained by typing about:config and then modifying the page. Make sure you take a back up copy just in case something goes wrong. Here are some of the hacks for the experimentally oriented.

Step one: Type about:config in the address bar and hit enter

Step two: Make the following modifications to the file by typing in the values on the respective fields to get the desired result (feel free to experiment)

1. To enable/disable Single Click Select URL of address bar

browser.urlbar.clickSelectsAll = True 
browser.urlbar.clickSelectsAll = False

2. To auto Complete URL while typing in the address Bar


3. To set the number of auto complete URL in the address bar

browser.urlbar.maxRichResults = #

(# indicates the number of auto complete URLs shown. The default is 12)

4. To disabler Browser Toolbar Tip = False

5. To paste copied content by clicking the center button on the mouse

middlemouse.paste = True

6. To disable blinking text

browser.blink_allowed = False

7. To create a single close button to for all Firefox Opened Tabs.

browser.tabs.closeButtons = 3

8. To increase number of recently closed tabs.


9. Right click view source in your editor

view_source.editor.path= Path of Editor 

10. To enable fast scrolling across tabs

toolkit.scrollbox.scrollIncrement =75

11. To stop displaying website icon in address bar and on the tabs = False

12. To enable spell check in text fields

layout.spellcheckDefault = 2

13. To speed up the browser

network.http.max-connections 30 to 96
network.http.max-connections-per-server 15 to 32
network.http.max-persistent-connections-per-server 6 to 8
network.http.pipelining false to true
network.http.proxy.pipelining false to true
network.http.pipelining.maxrequests 30 to 8
network.http.pipelining.ssl false to true
network.http.proxy.pipelining false to true

14. To disable annoying browser behavior

Change the followowing values to 'false'


15. To show more tabs on single window

browser.tabs.tabMinWidth = 75

16. To display search results in new tab

I have used many of the above about:config hacks with Firefox 2 before and it is working for the new version as well. If some thing goes wrong after applying these changes, restore your about:config to older setting.


Using Software to Fine Tune Firefox 3

People will be coming out with more helpful hacks, useful tips, tweaks and tricks soon. FireTune is a simple freeware utility that will help you to fine tune Firefox 3. It is meant for tuning network related settings and is done with respect to your computer speed and Internet speed. This saves your lots of time which you would waste while doing this optimization manually. Click here to download this utility. If you feel that the changes done with Firetune are not upto the mark then you can always revert back to your original settings.

How to Easily Save All Images and Media Files

One other interesting feature I have fond in Firefox 3 is that you can easily save all media and image files. To do this first you need to click on the site identification button sitting just left to the address bar. A “Manage Information” Button will pop up. Click on it and you will see another popup with lot of options. Select the Media Option. Here you can see all the images and other media files availble in that web page. Select any or all, then click on the Save As button. This will ask you to specify a folder where it will save all the media and image files.

I am also using flashblock extension which blocks all annoying video and flash contents and help the pages to load faster. Interclue is another useful add-on I have installed, which helps me see less and know more, click less and do more, and warns me of dangerous sites.

Firefox 3 Easter Eggs

Like most of all other softwares, Firefox 3 is also carrying easter eggs!

To see the first easter egg in Firefox 3, type about:Mozilla in the address bar and hit enter. You can see the following text appear on the screen, (white text in maroon background). "Mammon slept. And the beast reborn spread over the earth and its numbers grew legion. And they proclaimed the times and sacrificed crops unto the fire, with the cunning of foxes. And they built a new world in their own image as promised by the sacred words, and spoke of the beast with their children. Mammon awoke, and lo! it was naught but a follower.

from The Book of Mozilla, 11:9 (10th Edition)"

To see the second easter egg type about:robots into the Firefox 3 address bar. The following will appear!

"Welcome Humans!

We have come to visit you in peace and with goodwill!

* Robots may not injure a human being or, through inaction, allow a human being to come to harm.

* Robots have seen things you people wouldn't believe.

* Robots are Your Plastic Pal Who's Fun To Be With.

* Robots have shiny metal posteriors which should not be bitten.

And they have a plan."

There is a button saying "Try Again". Try it!

      While Facebook doesn't quite allow you the same degree of profile customization that MySpace does you can still tweak the look of your personal profile and apply some really nice looking Facebook Layouts to your profiles.

      Thanks for the write-up and some useful comment additions. When I typed: "about:config" I received a warning message saying "This might void your warranty".

      The message could be concerning for the more novice user wanting to fix a FF problem. Maybe a note within the hub that explains, because your reading this Hub you do know what you’re doing, unless you start changing things not directed. Although I can't understand what warranty will be voided in the first place?

      Firefox 3 is packed with lots of cool features. It also have the capability of detecting some security issues and vulnerabilities, which firefox 2 was not able to pick out.. It also sends quick alerts on noticing vulnerability.

      I have also noticed that it is faster than the previous versions. The video customization options allows you to save video files in different formats including flv, mp3 etc. However, it seems that it is less robust and stable. It crashes when loading or reloading some pages or when it encounters little error.

      After about 3 years with Firefox I have just switched to Flock. I upgraded to Firefox 3 and found it less stable. Flock is built on the same engine, so very familiar for firefox users. You can use most of these tweaks and most Firefox addons are compatible. I believe that Flock is in the lead at the moment and it has lots of great social networking features.

      Good tips. My favorite tip not mentioned here is to change the address bar so that it automatically does a google search (not an &quot;I'm feeling lucky&quot; search) for anything that doesn't resemble a URL. That way, I no longer need a separate search box.

      Thanks for the hub!

    • dougmcunha profile image

      Good article. Tweaking aboud:config settings is now part of Firefox user routine, although we never know what to change.

      We have to be selective about what we change in about:config. Most &quot;how to turn Firefox faster&quot; articles around the internet suggest changes to config which reduce memory usage to improve overall performance. But it have an opposite effect. Using less RAM increases the use of virtual memory, which is a place in your hard drive used like memory. Once RAM is much faster than hard drive, it's a bad idea stop using it in favor of much slower hard drive.

      When I found that you did not fall into this trap, it was a good surprise.

      As someone with comparatively little computer know-how, I've found that (even though I'm a total MAC girl) that MAC requires you to upgrade your Operating System which you can't do until you buy a new computer, and so on and so on. I've seen this happen attempting to updgrade SAFARI and FIREFOX. Frustrating. Do PCs work the same way?

      I found 3.01 upgrade is the best tweak you can do. I was having endless problems with 3.0 crashing, but 3.01 really helped.

      13 years ago from San Diego Area

      There's no doubt that Firefox is quicker than I.E.. One thing I have to be careful of is opening up too many link windows as it can overload resources and freeze everything.

      Thanks for in the info about the icon to the left of the add. window and being able to download media files from a page that way. I wasn't aware of that.

    • joer4x4 profile image


      13 years ago from Philadelphia, PA

      Actually the file you are changing is prefs.js. If you mess it up and didn't take a backup you can delete it. Firefox will create a new standard one when restarted.

      Not to take anything away for the author but the "To speed up the browser" sections should not be taken lightly. If you don't understand what you are doing you could just a easily degrade performance. You really need to experiment and put the time in to get it right for your installation. Not something I would recommend except to those who are technical. The problem lies in the balance of the communications (your ISP) and the user interface which also plays a part.

      Otherwise nice article!
