Hello firefox-dev,

Just a few weeks ago, the Firefox Desktop team got together to share notes, collaborate, and talk about the recent happenings in the code base. A few of us stuck around after the meeting to turn the meeting notes into something a little easier to digest. Enjoy!

Special thanks to Katherine Patenio who put these notes together with me.

Highlights

  • Firefox 92 was released today!

  • We’re 96% through M1 for Fluent migration! Great work from kpatenio and niklas!

    • [Screenshot]

      • Caption: A graph showing how Fluent strings have overtaken DTD strings over time as the dominant string mechanism in browser.xhtml. As of September 2nd, it shows that there are 732 Fluent strings and 32 DTD strings in browser.xhtml

    • Fluent is our new localization framework

  • We have improvements coming soon for our downloads panel! You can opt in by enabling browser.download.improvements_to_download_panel in about:config.

  • Nightly now has an about:unloads page to show some of the locally collected heuristics being used to decide which tabs to unload on memory pressure. You can also manually unload tabs from here.

  • As part of Fission-related changes, we’ve rearchitected some of the internals of the WebExtensions framework - see Bug 1708243

    • If you notice recent addons-related regressions in Nightly 94 and Beta 93 (e.g. like Bug 1729395, affecting the multi-account-containers addon), please file a bug and needinfo us (rpl or zombie).

Lint, Docs and Workflow

Password Manager

  • Welcome Serg Galich, he’ll be working on credential management with Tim and Dimi. 

Search and Navigation

  • Drew landed some early UI changes, part of Firefox Suggest, in Nightly. In particular, labels have been added to Address Bar groups. A goal of Firefox Suggest is to provide smarter and more useful results, and better grouping, while also improving our understanding of how the address bar results are perceived. More experiments are still ongoing and planned for the short future.

  • Daisuke landed a performance improvement to the address bar tokenizer. Bug 1726837 

Below the fold

  • [mconley] I did an “Intro to Firefox Desktop Engineering” that I recorded and put on YouTube while livestreaming. Maybe useful for folks who want foundational underpinnings on some Firefox Desktop concepts.

This information, including all of the previous updates, are fully available in this doc: https://docs.google.com/a/mozilla.com/document/d/1u9YH3ULNRYg6G-fN-Udkvfkcvg0alJfzi_zIAfFNkL8/edit?usp=sharing


Also note that I'm really just synthesizing and humanizing the stuff that's on the Wiki, which is freely available from here: https://wiki.mozilla.org/Firefox/Meeting, so check that out if you want the source material. It'll also be posted (minus the Below the Fold stuff) to the Nightly blog.


Finally, if there's a Firefox-ish team that you feel isn't being represented here, please let them know about the above meeting so we can get their updates.


Keep on rockin' the free web,


-Mike
