My Favorite Firefox 3.6 Config Tweaks

It’s no secret that I love Firefox, and what really makes me love it is how customizable it is. I already told you about the plugins I have… and here are my favorite config tweaks.

How to edit your config preferences, type the following in your address bar:
about:config

Change minimum width of the tabs to 75 rather than 100:
This makes your tab bar shorter, thus displaying more tabs before you have to scroll. Cool shit, yeah?
browser.tabs.tab
MinWidth Modified Value: 75

One close button to rule them all:
My favorite setting! Make the close button only appear at the end of the tab bar, rather than at every tab.
browser.tabs.close
Buttons Modified Value: 3

Disable prefetching of sites:
This will save up on your bandwidth, stopping FF from randomly guessing what you’re going to click and preloading them.
network.prefetch-next
Modified Value: false

Extend Spell check to forms: 
Add spell check to forms.
layout.spellcheckDefault
Modified Value: 2

Increase History Undo Close Tab Limit:
Undo Close Tab 15 times rather than just ten (recently closed tabs)
browser.sessionstore.max_tabs_undo
Modified Value: 15

Always open tabs in far right:
It’s really annoying when a tab opens next to another tab rather than at the end of the tab que where it belongs.
browser.tabs.insertRelatedAfterCurrent
Modified Value: false
