These Weeks in Firefox: Issue 59


  • Wow, what a weekend! Hopefully your add-ons are all working now.
    • A small set of users are still reporting add-on outages. We suspect that the Master Password and Anti-virus software are interfering with the original fix for those users. We’ve released 66.0.5 to try to handle those cases.
  • Outreachy interns for this summer have been announced
    • Mozilla is mentoring 8 students in this round. Thank you to all the mentors and all the applicants!
  • The Google Summer of Code students and projects have been publicly announced! Check out what folks will be working on this summer!
  • MattN wrote a blog post summarizing the Password Manager Improvements in Firefox 67

Friends of the Firefox team

Here’s a list of all resolved bugs.

Fixed more than one bug

  • Kestrel
  • lloan:[lloanalas]
  • Mohd Umar Alam [:umaralam48]
  • Neha
  • Tim Nguyen :ntim

New contributors (🌟 = first patch)

Project Updates

Activity Stream

  • A new Contextual Feature Recommendation for Sync is coming to the bookmark Star UI

"Sync your bookmarks everywhere" recommendation in the star UI

  • A lot of improvements and fixes to the new Pocket New Tab, specifically around network failure states.

Add-ons / Web Extensions



  • Rebranding going on this week.
  • The team is working on polishing the extension for an initial release, and then integrating the extension into desktop Firefox.

Firefox Accounts

  • Ed and Vlad are finalizing the sign-in UX for Fenix, our next-generation Android browser 🚦
  • Ed landed Rust APIs for FxA device registration and New Send Tab. Grisha is working on integrating this into Android Components so that Fenix can use it 📑

Sync and Storage


  • Jonathan and JR are bringing Push for internal Mozilla consumers (New Send Tab, FxA verification) to Fenix! 📣

Browser Architecture

  • RKV conversions have been rolled back for now while we investigate issues migrating from 32-bit to 64-bit builds.
  • browser.html conversion ready to go, but waiting until the next cycle.
  • Fluent cache for chrome documents ready to land. This will fix corner cases where DOM mutations might not trigger Fluent updates.

Developer Tools


  • Jefry Lagrange added a way to export console output to a file in bug 1517728.
  • “Copy as Fetch” and “Use in console” have been added to the network monitor context menu in bug 1540054.
  • When CSS warnings are displayed in the console, you can now expand them (like a console group) to reveal all the DOM nodes that this warning applies to. So it allows you to jump from a CSS warning in the console directly to the inspector.

  • Work on DOM & Event breakpoints started
  • Progress with captured stacks for various errors appearing in the Console panel (for web developers) or Browser Console window (for browser + addon developers).


  • Local HTTP requests are marked as secure now (bug).

Android Components

  • Support for built-in WebExtensions has been added! The new Reader View feature component (in Fenix and Reference Browser) is built on top of this.

Password Manager


Performance tools

  • Welcoming Raj Meghpara, our new GSoC student! He’s going to work on Instruments import support for Firefox Profiler.
  • Network tooltips are now displayed as soon as the line is hovered.
  • The publishing flow has been streamlined (ux issue)

    Is it possible you use a android version Firefox doesn’t support anymore?
