Firefox crashs random time with message "pure virtual method called" or "Segmentation fault" when meet internet page - NOT local page - has javascript global call - not in method - "window.alert()".
That page generated from J2EE/Spring and its character encoding is UTF-8, it try to show Hangul (Korean) text using "window.alert()".

I'm so sorry it's wrong report. please close this.
this is problem of "Firecookie" with "segmentation fault" and "Inline Code Finder for Firebug" with "pure virtual method called".

(but... I learned how to backtracing process... so I think it's not bad. :D)
