Consensus & Standardization

After a feature ships in Chrome, the values listed here are not guaranteed to be up to date.

  • No signal
  • Shipped/Shipping
  • Positive



While Firefox hasn't expressed any explicit signal, engineers weren't opposed. Filed https://bugzilla.mozilla.org/show_bug.cgi?id=1314686 for Firefox to match Safari and Chrome as well. Edge doesn't use a moving URL bar so this doesn't apply there.
