Configuration Mania replaces about:config

January 27, 2009

props again to Tekzilla

For those who frequently access about:config via the Address Bar, there is now an add-on, Configuration Mania, that makes it even easier to manipulate those settings, especially for those who are uncomfortable with the geeky feel.

To get Configuration Mania, go to


Now, click on ‘Add to Firefox’


Click ‘install now’ to install the Configuration Mania Firefox plug-in (add-on)


After Configuration Mania installs, it will ask you to restart Firefox for the new settings and change to take effect.


Firefo will inform you that it will try and restore your open tabs when it restarts. This has always worked for me, so I wouldn’t worry about it.

When Firefox restarts, you can access Configuration Mania via ‘Tools’ and ‘Configuration Mania’.


Configuration Mania will look like this:



Stop Firefox Download Manager from popping up

January 27, 2009

There are two ways to prevent the Firefox Download Manager from popping up.

First way:

props to Tekzilla for this tip.

1. In the Address Bar in Firefox, type “about:config”, without the quotes and no space before ‘config’


2. In the filter bar, type

3. double click it, making sure the value turns from ‘true’ to ‘false’, and restart Firefox

Now, when you download a file, the download manager won’t pop up annoyingly. but remember to clear the download history, as that will still exist. To do so, click ‘Tools’, then ‘Downloads’, and ‘Clear’.

Second way:

1. Go to ‘Tools’, then ‘Options’.

2. On the ‘General’ tab, uncheck the box next to ‘show the downloads window when downloading a file’, and click ‘ok’.


Speed Up Firefox via about:config

January 19, 2009

source: two videos from Tekzilla,


1. 1. In the address bar, type “about:config”, and in the filter bar, type network.http to filter the list

2. 2. Double click “network.http.pipelining”, which changes the value from false to true.

3. 3. Double click “network.http.proxy.pipelining” to change it’s value to true

4. 4. Double click “network.http.pipelining.maxrequests” and change the value to 30.

5. 5. Next, close the and restart the browser to have the changes take effect, the next time a page loads, you should see a noticeable increase in the speed at which it loads, because instead of loading each thing one step at a time, it loads everything at once.


1. 1. In the address bar, type “about:config”

2. 2. Right click anywhere and choose “new”, then “integer”

3. 3. Name the new integer “nglayout.initialpaint.delay”, press “ok” and set the value to “0”. This is the amount of time the browser waits before it acts on information it receives.

4. 4. While it doesn’t load the page any faster, it lets you see what has been loaded sooner.
