Round Table

Triage & Backlog Health

• Reminder:

  • ~20 untriaged bugs older than 3 months still pending.

• Team encouraged to:

  • Reduce NI backlog

  • Keep triage flow moving despite high workload

Coverage & Risk Awareness

• Reduced coverage expected later in the week (Thu/Fri risk window).

• Triage coverage adjusted:

  • Sunil covering for Valentin later in the week

Happy Eyeballs (HE) Rollout & Metrics

• Team encouraged to enable Happy Eyeballs flag in Nightly:

  • about:config → network.http.happy_eyeballs.enable = true

• Goal: gather more real-world performance data.

• Ongoing work:

  • Metrics collection

  • Profiler marker improvements

• Next phase:

  • Transition toward MASQUE-related performance testing in April.

LNA (Local Network Access) UX Feedback

• UX feedback reviewed (Figma prototypes).

• Key takeaway:

  • Users prefer simpler, less technical messaging for prompts.

• Ongoing improvements:

  • Reduce confusion around access prompts

  • Improve clarity without overwhelming detail

DevTools & External Collaboration

• DevTools team still interested in networking progress.

• Work currently deprioritized due to other initiatives (e.g., post-quantum).

• Continued coordination expected via:

  • Ad-hoc syncs

  • Slack communication

Team Check-ins (Highlights)

• Valentin

  • Working on cookie improvements, including removing nameless cookies.

  • Continuing LNA-related fixes and coordination.

• Oskar

  • Investigating HyStart++ performance anomalies:

    • Early connection losses

    • Slow-start exit behavior

  • Next step: filter out non-established connections and analyze logs.

• Max

  • Progress on Happy Eyeballs:

    • Metrics + profiler markers implemented

  • Work temporarily slowed due to dependency on patches.

  • Preparing for performance tooling adaptation (Cloudflare testing) for MASQUE.

• Lars

  • Continued performance investigations.

  • Identified issues via Cloud tooling.

  • Exploring potential Berlin visit (June timeframe).

• Sunil

  • Progress on LNA for workers (patch ready for merge).

  • Working on speculation rules / prefetch integration.

  • Coordinating with DevTools on workflow impact.

Important Business

Priority Queue

Active Projects

FEISTY

• Downloads GCP migration complete and under final validation.

• Downloads now unblocked.

DoH Enablement (Fenix & Focus)

• Continued monitoring of Nightly experiment.

• Observed:

  • Increased DNS latency under TRR vs native (early data).

• Expected improvements from:

  • Happy Eyeballs rollout

  • Socket-thread optimizations

Local Network Access (LNA)

• Desktop rollout complete; Android ongoing.

• Key work:

  • LNA for workers (landing soon)

  • Prompt UX improvements

  • Certificate mismatch handling

QUIC / HyStart++

• HyStart++ landed with metrics.

• Nightly experiment ongoing.

• Investigating:

  • Early connection loss patterns

  • Slow-start behavior inconsistencies

Happy Eyeballs

• Metrics + profiler instrumentation complete.

• Next phase:

  • Broader testing

  • Integration with performance tooling

MASQUE (Upcoming Focus)

• Planned transition in early April:

  • Use Cloudflare speed test endpoints

  • Compare H2 / H3 / HE / MASQUE configurations

• Max adapting Andrew’s tooling for this work.

Performance & Quality

• Continued improvements in:

  • Applink performance

  • Networking telemetry

• Tracker tailing experiments ongoing.

• Focus areas:

  • DNS latency under DoH

  • Connection establishment performance

  • Socket thread utilization

Decisions & Alignment

• Maintain PQ hygiene and triage backlog reduction.

• Proceed with Happy Eyeballs data collection.

• Transition toward MASQUE performance work in April.
