Python Plugin for Web Browser

[Sébastien Ramage]

I've an idea and I've made some search but I found nothing really
interesting.
There is somebody who have (or can help me to) try to developp a python
plugin for web browser just like java ??

I search an how-to for creating a plugin for Firefox and only find how
create extension...

I've find some informations about Python Active Scripting but this is
not what I want.
