Do you see a pattern? They are now abandoned software, although I made Checky and Diggler live a little longer (and I’m actually considering reviving Diggler) but they had their importance in my journey, and are part of the reason why I am where I am now.
Ten years ago, there was a new kid on the block. It used to be called Phoenix, it had just changed its name to Firebird. Eventually, it changed again for Firefox. You may have heard about it. Because Firebird was so much nicer than the browser in the Mozilla Suite, I started using its Debian package, and wanted my packaged addons to work with it. So I contacted Eric Dorland, Phoenix/Firebird package maintainer at the time, and got the addons working. I then ended up fixing a bunch of packaging issues.
This is how I got involved in Firefox packaging for Debian, and what eventually led me to work for Mozilla.
