I'm considering applying for this as I use Thunderbird for all my email, wrote a couple of XUL applications years ago, and have an Upwork account, and the first thing I need to do is to see what the source code and build process looks like: I've built Firefox and FirefoxOS before, and it was not trivial. Their post has nothing about that, and the Thunderbird page at Mozilla also has no "Developers", "Source code" or similar link anywhere. That should be there at least in the page footer. Ok, so here is the Mercurial repo and build instructions: https://hg.mozilla.org/comm-central/ https://hg.mozilla.org/comm-central/ https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Source_Code/Getting_comm-central https://developer.mozilla.org/en-US/docs/Mozilla/Developer_g... That link should be part of the job description. The directory size (du -sh) is 148 MB after "hg clone", and 5.4 GB after "./client.py checkout".
