Firefox + typeaheadfind extension

[Surya Kiran Gullapalli <skg fluent co in>]

Hi all,
I'm trying this garnome-2.14.0 and when i try to compile epiphany,
I'm getting this error,
You must not compile firefox with typeaheadfind extension.

I've compiled firefox with default settings only. How can i supress 
typeaheadfind extension in firefox. I've tried to see in firefox 
configure arguments, but i've found nothing.

Thanks in advance,
Surya
