Not working with Seamonkey 2.7.2

이 검토는 현재 부가 기능의 이전 (0.1.0) 버전에 대한 것입니다. 

Could you please elaborate a little?
Are there any entries in the error console?
Does the 'Add xxx'-menu entry show?
If yes, what happens?

This Add-On was developed using SeaMonkey 2.8, so I'll just set the compatibility...
