Some newbies have specific goals, some don't. When I was a newbie, my goal was to learn some programming. I started off with C++, which I don't think is very suitable for newcomers.

Thanks for the kind words! I would say Mozilla is in good hands and it seems to me that it's getting better and better.

Indeed, the intention was to make it easier to follow for everybody. Maybe I made a mistake :). Also, I'm not a Mozilla employee. Thanks for the feedback!

I'm just starting out on this road, so this is what I see right now. I'm sure my thoughts will become more nuanced and elaborated in time. Thanks for the feedback!

You should really check it out. Try contributing on a few easy bugs, get an idea about the people involved!

:) I'm learning! Thanks.
