Could you please add a new component named "JSMarionette" to the product "Firefox OS" in the production instance of Bugzilla?
can do - we'll just need a description for the component. see https://wiki.mozilla.org/BMO/Requesting_Changes#Components for other things you can set.
I've gotten some better guidance about this. Instead of adding the component "JSMarionette" to the "Firefox OS" product, it's been suggested that I ask for the feature-b2g flag to be added to the "Testing" product. I'll close this bug and open a new one. Sorry for the inconvenience.
