How to write Mac Osx specific Plugins for Mozilla Browser

[varmag]

Hi all,

I have to write a Mac Osx specific plugins For Mozilla.
Can any body suggest me how to proceed.
I am Not getting where to start, in widows i understood how to proceed using Visual studio and the mozilla pugin installer.
But in mac where to start and which IDE( like Xcode, eclipse) I can use to build a frame work(i.e. like windows win32guilibrary(dll) that we build using visual studio) that can be installed using Mozilla plugin installer.
I had experience in developing apps in XCode, is it possible to build a plugin from Xcode which can be installed using the Mozilla plugin installer please suggest me how to proceed( i.e. which project to select).
If it is not possible using Xcode please suggest me which SDK's I can go for in which IDE's they can be built.

Thanking You all in advance,
varma G

Plugin or extension?

They're two very different things.

I want to write a plugin not an extension.
Can we write a Mozilla plugin using Xcode?
If it is not possible with xcode, using which SDK and IDE can we write the plugin.

I read the topics in this website "http://www.mozilla.org/projects/plugins/"
It has the detailed information (step-by-step)of how to write a mozilla plugin in windows .
"http://www.mozilla.org/projects/plugins/npruntime-sample-in-visual-studio.html"

But Iam trying to write it on Mac and there is no such detailed information .
Thanking you.
