Global Menu Bar Integration on Gecko based software

view story

http://askubuntu.com – I am using Komodo Edit, a software based on Gecko (Mozilla). FYI, for now, it's not supported yet for global menu, still using classic menu. I have been trying searching till reached lauchpad, and just found rdf file. It is should be *xpi isn't it? But, just tried might be work, I downloaded it, and dragged it into add-on window. Like I expected, it didn't work. So, the problem is, Where I could get this 'globalmenu-bar intergration' extension in xpi? Or, if that (above) is not possible, how could I make the Komodo supported? Why am I asking this? From the downloaded rdf file of global (HowTos)
