Hey firefox-dev!

The Firefox Desktop team met earlier this week to discuss the latest goings-on and the what's-what in the codebase. We've taken the notes from that meeting and tried to condense it down into something more palatable for broader consumption.

Special thanks to Niklas Baumgardner who put these notes together with me!

Highlights

  • Firefox 106 went out today! Here are some blog posts talking about what is new, as well as the release notes!

  • The Unified Extensions toolbar button (part of the Manifest v3 project) has been enabled by default in Nightly.

  • Raphaël Ferrand added a patch to format the value of grid-template-areas in the inspector (bug)

    • [Screenshot]

      • Caption: The `grid-template-areas` portion of the Rules pane of the DevTools Inspector displays the names of the grid sections in a grid to make it easier to map their names to their locations.

  • Emilio is burning away XUL layout! See his mailing list post here for details.

  • Power profiling now works on Linux and MacOS with intel CPUs. (previously only worked on MacOS with Apple Silicon and Windows 11). Thanks Dan Robertson for the work on the Linux patch!

Developer Tools   

DevTools

  • Wartmanm fixed a bug in the console autocomplete when the debugger is paused (bug)

  • Zachary Svoboda made it so the JSON Viewer gets automatically focused on load, allowing to scroll in the page via the keyboard easier (bug)

  • Fabien Casters fixed an issue in the Netmonitor Raw header where text selection wouldn’t persist (bug)

  • Alex made the iframe we use in the Netmonitor to render HTML responses more secure, ensuring it runs in a content process  (bug)

  • We fixed an annoying bug in the console input where hitting the Fn key while having text selected would delete the selection (bug)

  • Honza fixed half a dozen of bugs on our documentation (bug, bug, bug,  bug, bug, bug)

  • The debugger source tree in Browser Toolbox is now sorted thanks to Alex. The main thread will always appear first, then all processes sorted by pid, and finally workers (bug)

    • [Screenshot]

      • Caption: The debugger source tree in the Browser Toolbox showing a list of threads, starting with the Main Thread, followed by threads in various subprocesses sorted low to high by their process ID.

  • Alex is also leading an effort to properly maintain our sourcemap package (https://github.com/mozilla/source-map), which a lot of people are using as it’s faster than Chrome/Safari implementations. He has promising result to make it even faster, hopefully we’ll share some numbers in the weeks to come

WebDriver BiDi

  • James fixed handling of undefined in pointerMove and wheel actions (bug)

  • Sasha added Realm support to `script.evaluate`, `script.callFunction`, and `script.disown` so you evaluate script in a given realm (bug)

  • And she also enabled `script.evaluate`, `script.callFunction` and `script.disown` on release (bug).

  • A new version (v0.32.0) of geckodriver was released, with better support for Firefox in Snap containers (issue)

  • Julian added support for `referenceContext` parameter for the `browsingContext.create` command (bug, spec), so the new browsing context would be physically inserted after the referenced one.

  • Henrik fixed a bug where local IP addresses would cause Remote Agent to start WebSocket on IPv6 instead of IPv4 (bug)

  • Sasha added support for serialization of complex objects (bug)

  • Finally, during the AllHands, Sasha prototyped a WebConsole UI using WebDriver BiDi (bug). This lives on https://firefox-dev.tools/bidi-webconsole-prototype/ 

    • [Screenshot]

      • Caption: A WebConsole that looks very similar to the Firefox DevTools console, but running within a web page and connected to a local Firefox for logging and script execution.

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
