about:config hacks in Firefox 3

This is going to be a quick tutorial of a few of the cool things you can do with the Firefox 3 about:config window.

The about:config window lets you change pretty much all of Firefox’s settings. Be careful when you’re adjusting your settings, as you can give Firefox brain damage

To open the config window, in the address bar type about:config and press enter

Here are some of my favorite hacks for Firefox 3:

1. Disable Extension Compatibility Check

extensions.checkCompatibility = False
extensions.checkUpdateSecurity = False

2. Disable Prefetch (if you do a lot of Google searches)

network.prefetch-next = False

3. Enable spellcheck in forms

layout.spellcheckDefault = 2
Change Value from 1 to 2

4. Don’t allow <blink> text (annoying!)

browser.blink_allowed = False

5. Some network speed tweaks:

network.http.pipelining false to true
network.http.pipelining.maxrequests 30 to 8
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.ssl false to true
network.http.proxy.pipelining false to true

6. Show More Tabs

browser.tabs.tabMinWidth = 50

Setting lesser value with reduce Tab width. By default 12 will show at 75 pixels.

7. Disable or Set Short Delay Time While Installing Firefox Add-on

security.dialog_enable_delay = 0

Set to 1 if you only want to wait 1 second.

8. Increase History Undo Close Tab Limit ( Recently Closed Tabs )

browser.sessionstore.max_tabs_undo=25

Only 10 by default

9. Open Firefox Default Search Bar Result in a new tab:

browser.search.openintab=True

10. Right Click View Source in Your Favorite Editor

view_source.editor.external=True
view_source.editor.path= Path of Editor

(e.g. path C:\Program Files\geany\geany.exe)

Enjoy!
