Triage Process

If you're triaging bugs in a component, Triage Process for Firefox Components in mozilla-central and Bugzilla is the process we follow.

Initiative Process

There are a number of workflows in Bugzilla that are in addition to and often across our Component system. These initiative will modify our Initiative Template and the modified document will be linked below. Any special tagging required by these initiates will be registered as Metadata and also described in the Initiative document.

  • Performance Initiative - Triage and tracking of bugs we believe are essential to Firefox's responsiveness and throughput. NOTE: Update of the Quantum Flow initiative.

Triage Scorecard

Triage status of unresolved bugs in Core, Firefox, Firefox Android, Firefox iOS, and Toolkit (excluding general and untriaged) without open needinfos filed since 2016-06-01

History is viewable as a Re:dash dashboard

Bug Farming

Automated cleanup of bugs is handled by the bug-husbandry-bot, under which regular and ad-hoc queries run.

Current Regular Queries

Intermittent Test Failure Cleanup

Resolves bugs filed from Orange Factor for intermittent test failures. Intermittent test failure bugs which have had no new failures in 21 days (as measured by comment count) and have not been reopened in the past week are resolved as INCOMPLETE.

Inactive Bugs

Resolves bugs in Firefox-related components which have no activity in at least one year. These bugs are resolved as INACTIVE.

Other Requests

File a bug in the Bulk Bug Edit Requests component.

Per-release Triage Queries

Firefox 60 Queries

First nightly 2018-01-22

P1 bugs which are affecting for Firefox 60; these bugs should be reviewed to see if they are still P1s and if they should not be wontfixed.

Bugs for which we don't know if they affect Firefox 60 by triage status; un-triaged bugs should be reviewed as early in the cycle as possible.

Bugs filed later in the cycle should only be considered if they will result in a dot release if they are not addressed.
