Mozillian, member of the French speaking Libre Software Users' Association (AFUL) and Debian GNU-Linux user. I develop web standards valid and accessible web sites/web app, as well as pure AJAX applications.
I was an active contributor to Mozmill, a testing tool and framework for writing automated tests for Gecko based applications (Firefox, Thunderbird, etc.) and I contributed tests for Firefox.
On MDN I'm adding code and notes or updating content as I stumble upon documents needing update or when I find difficulties developing something that could apparently be more documented.
My aims are to help others, as much as I have been helped by Mozilla, and to make more and more people to decide on using the Mozilla platforms.
