Developing Add-Ons for Firefox

In April 2008 I gave two talks about Firefox and XUL Development at the biggest open-source conference in Brazil. Here is the video of one of them (in portuguese), about Extension development for Firefox 3. More details will come soon, as I finish doing some polish in the presentation and examples for them to be useful for everybody who is interested, in not only for those who attended the conference.

  3. I like to talk about places and share what goes on in my community. Guam is the place I live and hope to get business partners to link together for those who like to learn more about other people’s blogs and what they enjoy doing most. I do not understand any other language other than english. It was due to my up bringing. It doesn’t bother me to tell people that but I know it can be down fault for me. That does not mean it’s the end, but I hope a true beginning to open up more ideas and more opportunities that work for those who love to interact. I am a fan of mozilla firefox and I do use other extensions for the reasons of how I interact quickly to reach others. This is important in any business. So for second languages. I hope to find freinds who can openly educate me and their friends.
