Aki recently added some new features to MozHarness which make it much easier to create multi-locale Fennec builds.

Creating mutli-locale Fennec builds has always been tricky, but at the same time, its also important. Simplifying this process makes it easier for developers to recreate locally what Mozilla will eventually ship to end-users, as well as make it easier to debug problems reported by our multi-locale aurora/beta Fennec users – always a good thing!

Aki’s posted a short summary of steps to the Fennec wiki page. For more details, see Aki’s blogpost. Please give this new code a try… and of course, if you find something that you think should be changed to make this better, let Aki know or file a bug in mozilla.org:ReleaseEngineering.

Nice work, Aki,
