We are in the process of closing Fig down and merging to mozilla-central. We'd like to stop nightly builds and updates ASAP.
Nightly builds will stop if code is no longer landing, but we can certainly reset Fig back to standard state for a disposable branch. Either now or when we know what the next user wants is fine.
FYI: I've just merged fig to m-c. I'd wait until the next Nightly is built and we confirm everything is running fine, just in case.
Update: It's safe to reset fig back to disposable state now as it has been fully integrated in m-c and the first nightlies have already been build.
Resetting on bug 970491.
I don't think there's anything else to do here...
