Many tutorials about chrome extension development but not plugins. Anyone can answer me, what's the relation between chrome plugin and mozilla plugin? How to make a mozilla plugin working in chrome?

Thanks for any help.

A Chrome plugin, is built using html and JavaScript. In essence, like a normal webpage.

A Firefox plugin uses a language called XUL instead of html.

There are also differences in how they are allowed to manipulate the browser interface, so direct porting is probably difficult.

As an example, look at the difference in how the stumble-upon extensions work. In Firefox, the interface is allowed an entire toolbar, always visible. In Chrome, it is merely a button, that when pressed, creates an HTML toolbar, which gets injected into the page you are currently viewing.

Some form of human back-engineering effort is probably a requirement...

I heard that chrome can use firefox plugin directly, however, not extension. Such as flash player plugin, and O3D. It seems that's based on Mozilla plugins. But I have problem to get mozilla sample plugin work on chrome.

Any idea about that?

I have no idea about plugins in chrome (other than XPCOM does not work in chrome, alot of people trip on that one).
But if you have a look around youll find some source examples that might help, heres some from google.code

Theres also a post around here somewhere that I think I mentioned a couple more projects

No..... it's not that Chrome can use Firefox plugins, but rather Chrome can also use NPAPI plugins (which is also used by Firefox).

So don't say based on "Mozilla plugins"; you mean based on NPAPI plugins.

That'd be an extension, plugins are different in Chrome.
See chrome://extensions vs. about:plugins
