Review and authoring guidance for new/changed tests in the Fenix TAE efficiency framework (mobile/android/fenix/app/src/androidTest/java/org/mozilla/fenix/ui/efficiency). Use when reviewing a diff, PR, or Phabricator revision that adds or modifies files under that path — page objects, selectors, navigation edges, or test files. Also use when authoring a new test and self-checking before submission, when asked to check a test against TAE conventions, classify a test (presence/interaction/behavior), or judge whether a helper belongs in a page object vs. BasePage. Applies the framework's principles and anti-patterns as a review rubric with severity tiers.

End-to-end New Tab train-hop targeting for the Experimenter repo. From a single trainhop version string, files the GitHub targeting issue, branches, adds the NimbusTargetingConfig entry, lints, and stages a drafted commit. Use for "newtab trainhop targeting" requests.

Durable review guidance for Firefox's built-in IP Protection (VPN) module, covering panel UI, proxy/channel filtering, authentication, telemetry, and localization.

Use after tests pass on a Nova feature — before linting or formatting — to annotate changed files with @nova-cleanup instructions for post-launch automated cleanup.
