Project Updates

Add-ons

  • No updates this week.

Activity Stream

  • ‘Graduation’ team is getting close to preffing on Activity Stream in Nightly and working on Search Suggestions, about:home, cleaning up tests, and perf telemetry
    • Aiming for more regular / weekly landings from github to mozilla-central
    • Replaced custom React search suggestions from Test Pilot with existing contentSearchUI used for about:home/about:newtab simplifying tests
  • Test Pilot team is finishing up customization (drag’n’drop, add/edit topsite), as well as beginning work on Sections
  • Activity Stream, when enabled on m-c runs in the content process!
  • Removed most of Content Services / Suggested Tiles code from about:newtab resulting in perf improvements and removed / ~8x fewer intermittent test failures

Electrolysis (e10s)

  • The e10s-multi team is still looking over the data being gathered from the Beta population against the release criteria to determine whether or not e10s-multi will ship in Firefox 54, or will have to wait until Firefox 55
  • e10s-a11y support in Firefox 55 has been marked “at risk” due to stability issues. A go/no-go will be happen no later than June 3rd
  • erahm has a blog post about how memory usage with 4 content processes continues to be the sweet spot

Firefox Core Engineering

  • We’re officially shipping the streamlined stub installer in 55 (this is Windows only). You can see it as of tomorrow’s Nightly.
  • Reminder: 55 is also installing 64bit by default on 64bit OS; updates come later.
  • Resolved race condition in Rust runtime. This may have been bugging some tests (no pun intended).
  • We have preliminary top crashers lists from crash stacks sent via crash pings. Expanding that analysis is pending review of the data & correlation with crash reports.
  • Just started week 3 of the Flash Shield Study. Preliminary results: Flash usage is reduced by 75%
  • Flash is CTP by default on Nightly, and on track to Release 55.

Form Autofill

Lint

  • The previously mentioned hooks for ESLint will now automatically update ESLint’s setup if needed.
  • The mozilla/recommended configuration is now default for the whole tree. Directories which don’t use all the rules are whitelisted. We’ll work towards reducing those.
  • There’s been more improvements for using eslint-plugin-mozilla outside of mozilla-central, and it is now being used by various github based repositories including screenshots, activity stream, pdfjs

Photon

Photon Engineering Newsletter #1 out last week, #2 coming later today.

Performance

Structure

  • The page action menu has started taking shape and now has items to copy/email links, and will soon have a ‘send to device’ submenu;
  • Tomorrow’s nightly will have Firefox Account and cut/copy/paste items in the main hamburger panel;
  • Main work on the permanent overflow panel (as a replacement for the customizable bits of the existing hamburger panel) is done, working on polish and bugfixes;
  • Work will start on the new library button this week;
  • We’ll be working to flip the photon pref by default on Nightly in the next week or two;

Animation

Visuals

Onboarding

Preferences

  • Search is taking shape on Nightly! It now comes with the right highlight color, tooltips for sub-dialog search results. With the help from QA engineers, we are closing the gap between implementation & spec.
  • UX team asked us to revise re-org. The change will likely postpone re-org shipping by one release (to 56); the good news is the release population will be presented with the new search & re-org at the same time, if that happens.

Platform Audibles

  • No updates this week.

Privacy/Security

  • Mostly Containers work, see Test Pilot update.

Project Mortar (PDFium)

  •  :peterv made some progress of the JSPlugin architecture - the last few pieces of work are reviewing. Hopefully this is the final round of review, and we will land all of them (8 patches!) soon.

Search

  • One-off buttons in the location bar are ready to ride the trains in 55.
  • Search suggestions are now enabled by default. Users who had explicitly opted out of search suggestions in the past, will not see them.
  • Hi-res favicon improvements: the default globe favicon is now hi-res (SVG) everywhere in the UI and some ugly icon rescaling was fixed.

Sync / Firefox Accounts

Test Pilot

  • Containers experiment release 2.3.0 coming this week
    • adds a “site assignment” on-boarding panel to increase site assignments
    • removes SDK code
  • Screenshots: aiming for 55
    • Hoping WebExtensions will be performant enough by 55
    • Backup plan: move UI (toolbar button, context menu item) into bootstrap code, lazy-load WebExtension on click.
      • Currently in progress
  • We’re planning to start a Test Pilot blog (with help from Marketing)
  • Test Pilot and experiments are moving away from the SDK
    • Looking into replacing Test Pilot addon functionality with a > WebExtension API Experiment (learn > more)

This week I learned

  • async/await & promise can still jank. Use requestIdleTimeout instead(?)
