P.S. to reproduce: choose 5 (build spidermonkey), on "Would you like to run a configuration wizard to ensure Mercurial is" select yes.

Try this workaround: create an empty mozconfig file in your source directory.

Hello.

I've created an empty mozconfig & updated the repo with hg pull && hg pull update.
Now works like a charm!

Thank u very much for your help!

This was a very good first bug report, nice work! You've checked almost all of the boxes in the "perfect report checklist"™:

• ✅ Steps to reproduce
• ✅ Stack trace
• ✅ Confirmation that the fix worked

I'd just make one recommendation for future reports: Bugzilla supports Markdown-like styling, so I'd recommend wrapping multi-line terminal output in triple-backticks (```) so they get formatted nicely, like so:
