Firefox/Meeting/03-Jul-2018

General Topics / Roundtable

• We landed a large refactor to how we load favicons for sites. A few regression fixes have landed since and should be in today’s nightly. If you’re still seeing favicon issues please file a bug blocking bug 1453751.
• [felipe] browser_startup_content.js became a whitelist. This means that any new modules or JS-implemented components loaded during the content process startup will make this test fail unless it is added to the whitelist (with good justification). Also note that if something is removed from the startup path, it needs to be removed from the whitelist too, otherwise the test fails.
• [mak] Use blocking reviews when asking to multiple reviewers in Phabricator, otherwise it will be a first-come-first-serve. See the PSA thread I started in firefox-dev.

Friends of the Firefox team

Project Updates

Add-ons / Web Extensions

• Internal extensions (e.g., screenshots) regained the ability to run content scripts on the PDF viewer.
• The tabs API has been updated to understand tab multiselect.
• An API for working with search engines is close to landing.
• Extension-defined keyboard shortcuts can now use more combinations of modifier keys.
• Support for automatically updating LWTs to WebExtension themes landed. AMO will automatically migrate existing LWTs some time next month.
• Permission notifications from extension pages now display the extension name.
• Bugs related to delayed startup and storage API migration to indexedDB were fixed.
• Migration of existing bootstrapped extensions is creeping along.

Activity Stream

• Worked around an issue where Activity Stream completely fails to load with IndexedDB not working for ~half a percent of release users and uplifted to 61.0.1
• Nothing visual and shiny
  • A code mirroring PR that gets us one step closer to being a Firefox component (tracking) and allows developing directly from mozilla-central
  • Enabled CSP previously was Report-Only
  • Pieces from a bigger bug to use ScriptPreloader Cache
  • Various about:welcome fixes for Beta 62 experiments

Browser Architecture

• PSA: Upcoming regressions - XBL Replacement Newsletter Special Edition (read more on firefox-dev)
• XML pretty printing now uses Shadow DOM when available instead of XBL in the content process (bug). Planning to extend this with the “UA Shadow DOM” for other in-content widgets (videocontrols, plugin click to play, etc).

Lint

• Nothing to report

Fluent (read only)

Performance

• felipe has been working on more content process startup improvements, and ensuring we don’t regress them
• florian is working on about:performance improvements
• imjching is working on moving activity stream’s new tab page to its own content process
• imjching is also working on using the JS ScriptLoader cache to improve content process startup when it loads activity stream
• gijs landed another change to make blocklist processing faster
• mconley is working on reducing extraneous paints we’re doing

Policy Engine

• ESR only policies moved to machine policies on Windows so that can be used on RR (except search) and so they can be used on Mac/Windows
• Additional authentication prefs added.
• Ongoing work by Kanika on the about:policies page
• Lots of things marked for uplift

Privacy/Security

• Firefox Monitor shield study is live!
• Cert error page redesign landed
• War against innerHTML is in endgame: Johann looking into sanitizing DOMParser as well
• Privacy UI improvements (metabug): starting to work on v2 for 63

Search and Navigation

Address Bar & Search

• The Search Service is now caching the distribution id
• Proposal to support "application/json" as well as "application/x-suggestions+json" as MIME types for Suggestions in OpenSearch
• Fixed long UI hangs caused by the new autofill triggers
• Fixed a longstanding bug with autofill overriding bookmark keywords in the Address Bar
• Work is in progress to fix some inconsistencies of the new autofill algorithm
• Florian Hartmann has completed the first version of the federated learning addon (blog post), that will allow us to study and improve matching in the Address Bar
• Peter Simonyi has improved address bar suggestions with using a bookmark keyword, adding historical results to it

Places

• More work on the redesigned bookmarking panel
• Fixed a possible bookmarks dataloss introduced in Firefox 61, affecting profiles with incoherent bookmark roots. Fix will be in 61.0.1
• Removed the “Open bookmark in sidebar” feature
• Remove more more dead code driving the old bookmark descriptions

Other

• Standard8 has removed BrowserUITelemetry

Application Services (Sync / Firefox Accounts / Push)

• Ethan landed a client for Megaphone 🦊📣, a service for broadcasting “tickles” to all Firefoxes. We’ll use Megaphone for real-time app and blocklist updates, and other places where we currently use polling.
• Edouard landed a client for Firefox Accounts Commands ⏰, an extension of the FxA device manager to support features like lower-latency “new send tab”.
• Thom working on FFI changes in the new Rust Sync adapter 🦀.
