Hi! Thanks to you guys, We can use useful tool, the Firebug :) many thanks.
but... When i input Korean in intergrated command editor, and input another like Space, Enter, !, ? or any other leters, Korean words disapear.
It's same thought i reintall firefox and firebug, and change version to alpha, beta, or current both firefox and firebug.
please see a video which i uploaded... what should i do?
