How to change 'open link in new tab' behavior in Firefox 3.6 back to the old style.

I downloaded Firefox 3.6 yesterday and I see that the 'open link new tab' behavior is changed. In the previous version, an opened new tab will be inserted at the rightmost in the tab pane but now the new tab will be inserted next to the current related tab. It's just a style but I like the old one.
To change it back to an old style. Steps are below.

• Enter about:config in the location bar.


• Press "I'll be careful, I promise!" button. yes, you have to be careful about this.


• Type tab in filter box as in image.
  
  
  

  
  
• Find the preference name browser.tabs.insertRelatedAfterCurrent and double click it. The value of this preference will be toggled to false.

That's it.
