This is a reminder that the Nightly Soft Freeze is now less than a week
away. Please be mindful of any large or risky patches targeting Firefox
63 before the soft freeze begins and we begin merges to the Beta branch.

> Do:
> - Be ready to backout patches that cause crash spikes, new crashes,

> - Monitor new regressions and escalate merge blockers
> - Support release management by prioritizing fixing of merge blockers
> Do Not:
> - Land a risky patch or a large patch
> - Land new features (that affects the current Nightly version) — be

> - Flip prefs that enable new Features that were untested in Nightly cycle
> - Plan to kick off new experiments that might impact a feature's merge

> Please let us know if you have any questions/concerns.
