This material is largely out of date

The Firefox QA team is responsible for the Firefox browser -- both Desktop, (Windows, Linux, Mac) and Mobile (Android). Our responsibilities include qualifying builds prior to a maintenance or milestone release. Other responsibilities include, but are not limited to:

  • Verifying bugs using a triage strategy
  • Running basic functional tests and smoke tests - automated and manual
  • Running our automated test suites on localized builds
  • Running automated update tests across platforms, through all update paths, across localized builds
  • Making sure web content is ready for consumption

In addition to qualifying builds prior to a release, we perform ongoing tasks on the development branches to ensure no major problems get uplifted as we merge changes to the next branch. For example, on a daily basis we:

  • Confirm new unconfirmed bugs
  • Verify bugs on development branches like Aurora and Beta
  • Engage community and new volunteers in helping improve Firefox through test day events
  • Interact with developers to help them test the features they implement
  • Perform exploratory testing on new features while on the Aurora branch
  • Write test cases in Litmus for new features and user-facing features
  • Monitor crash-stats to assess stability
  • File and track new crasher bugs as they appear in crash-stats
  • Manage web compatibility testing through community involvement or crowdsourcing companies that help in testing hardware configurations and top-site testing

All of which help assess the quality of individual new features as well as the Firefox version as a whole.


Everyone is welcome to join us in testing and in our weekly meetings.

If you would like to help out, pick a task from One and Done, which has a list of ways to start testing. All the tasks are up-to-date and they have clear, step by step instructions!

Team Meetings

This team has been broken up and is embedded with the development teams. Channel Meetings is the best place to get an overview of what individuals are working on.

Feature Owners

Major features in Firefox are owned by a primary QA contact who is responsible for ensuring the proper testing of those features.

We encourage community members to try specializing in a particular Firefox feature so they gain knowledge in depth! Contact the feature owner if you would like to be a tester on their team.

Here's our current list of Feature Owners.
