Bug Triage
Warning: The bug that will overshadow all the hard work we put into the Firefox 57 release has probably already been filed. We need to find it and fix it.Contents
What we do
Mozilla's bugmaster develops policies and processes for managing bugs, their goal is to "leave no bug behind," and help Mozillians make crisp and actionable decisions on bugs, and enable them to follow-through on their decisions.
Triage Process
If you're triaging bugs in a component, Triage for Component Leads 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
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.

Firefox 57 Queries
First Nightly: 2017-06-12
P1 bugs which are affecting or fix-optional for Firefox 57; 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 57 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 for fixes if they will result in a dot release if they are not addressed.
Firefox 58 Queries
P1 bugs which are affecting or fix-optional for Firefox 58; 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 58 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.
