If you think that a lot of people are going to be impacted by a regression, ask release engineering to stop automatic updates. You can contact the on-call sheriff in the #sheriffs IRC channel or ask in the #releng channel.

Blocking automatic updates won't prevent people to get an update if they check manually for it in the About dialog. It will also not prevent new users to install Firefox Nightly from mozilla.org but it will mitigate greatly the impact on our existing user base.

We can ask for automatic updates to be stoped for a specific OS.


Most of the major regressions are reported immediately via our @FirefoxNightly Twitter account followers, usually when more than 2 people report a similar regression there is a high chance that it will be serious and stopping automatic updates should be done rapidly.
