Fission

Lint

New Tab Page

  • Finishing up some promo topsites changes for an experiment coming later.

  • Finished Discovery Stream responsive design updates.
  • Researching performance improvements for a personalization feature we’ve experimented with in the past to see if we can get something reasonable.

NodeJS

  • The NodeJS installed by `mach bootstrap` will be upgraded (probably today) to a new 8.* version to fix a security hole.
    • Will be announced in the usual lists/newsgroups when it happens
    • Old version of Node 8 probably will be unsupported (i.e. builds will break without an upgrade) later this week; need to chat with a few more folks about this.
  • NodeJS 10.x hopefully coming early in the new year; discussions still need to happen

    • Bug 1601761 - Enable the PiP audio toggle in nightly
      • Held to Nightly for now for testing and UI feedback

Privacy/Security

Remote Debugging (Chromium Protocol) (read only)

Priorities for our next deliverable in 2020 include Fission compatibility, the CDP Network domain and more upstream Puppeteer work.

We’ve made important progress in our support of CDP’s Page and IO domains:

  • Maja implemented parts of Page.createIsolatedWorld and Page.addScriptToEvaluateNewDocument to enable the creation of extra JavaScript execution contexts on page load.
  • Henrik implemented parts of Page.getLayoutMetrics to retrieve the layout (fixed) viewport and the full content size. Both are needed for better screenshot capabilities like capturing the full page.
  • Henrik added support for Page.printToPDF to allow the current web page to be printed to a PDF file. This also includes the implementation for handling streams via IO.read and IO.close.

Search and Navigation

Search:

  • Notable changes:
    • Removed the “Automatically update search engines” option, because it was confusing for users; built-in engines don’t respect it, most Search Engines installed don't support it, and it doesn't stop the engine lists changing (which is what some people thought it would do) - Bug 1444426
  • Search configuration modernization
    • No notable updates, work continues.

Address Bar:

Other:

  • Favicons added dynamically after the pageshow event, or with “Cache-Control: no-store”, are no more stored in Places - bug 1598371.
  • Fixed a regression in history where titles from sub frames could overwrite top frames titles, thanks Emilio! - bug 1601563
