General triage

Project Updates

Add-ons / Web Extensions

Addon Manager & about:addons

  • Changes to the add-on install flow: As anticipated in Firefox >= 100 user activation is now required to successfully trigger the add-on installation flows - Bug 1759737


WebExtensions Framework


WebExtension APIs

  • Fixed missing “title” property in the bookmarks.onRemoved event details - Bug 1556427
  • Fixed browser.sessions.getRecentlyClosed API when a closed windows had a tab with empty history - Bug 1762326

  • Added support for creating muted tabs using tabs.create - Bug 1372100

    • Thanks to kernp25 for contributing this nice enhancement

  • Support overriding the heuristic that Firefox uses to decide whether a theme is dark or light using the new “theme.properties.color_scheme” and “theme.properties.content_color_scheme theme” properties - Bug 1750932


Developer Tools

  • Toolbox

    • Wartmann fixed an annoying Debugger + React DevTools webextension bug, where you had to click the resume button twice when paused because of a “debugger” statement (bug)

    • Yury and Alex improved debugging asm.js/wasm project (bug), by turning debug code on only when using the Debugger, making using the console only faster

    • Julian fixed a bug when using the picker on UA Widgets (e.g. <video> elements)

    • Storage Inspector wasn’t reflecting Cookies being updated in private tabs, this was fixed in Bug 1755220

    • We landed a few patches that improved Console performance in different scenarios (bug, bug and bug), and we’re getting close to land the virtualization patch (bug). Overall the Console should be _much_ faster in the coming weeks, we’ll compile some numbers once everything landed

  • WebDriver BiDi

    • Support for the browsingContext.close command landed (bug) which allows users to close a given top-level browsing context (aka tab). The browser testing group still needs to agree on what should happen when the last tab (window) gets closed.

    • Optional hosts and origins should now be set as command line arguments, and not from preferences anymore (bug). This will raise user awareness when adding these additional hosts and origins that need to be accepted for new WebSocket connections by WebDriver BiDi clients.

    • Most of the existing Webdriver tests on Android are now enabled (bug), which will prevent regressions on this platform. More tests can be enabled once Marionette will support opening new tabs.

Lint, Docs and Workflow

  • There are various mentored patches in work/landing to fix ESLint no-unused-vars issues in xpcshell-tests. Thank you to the following who have landed fixes so far:

    • Leslie Orellana

  • Gijs has landed a patch to suggest (via ESLint) using add_setup rather than add_task in mochitests, and updated many existing instances to use add_setup.

  • Standard8 landed a patchset that did a few things:

    • Fixed an issue when running with ESLint 8.x which we'll be upgrading to soon.

    • Completed documentation for ESLint rules where it was missing previously.

    • Upgraded all the Mozilla rules to use a newer definition format, which also includes a link to the documentation.

      • Editors should now be able to link you to the documentation if you need more info e.g. in Atom:

Search and Navigation

  • [:mcheang] Welcome Stephanie! She’s here now, so let’s pass the mic to her for an intro!
  • James changed one of the observers we use for some search telemetry to a more efficient one, which also seems to have helped speed up some page load tests on Linux
  • Various patches have landed to improve search & new tab's support for live language switching, including correctly switching search engines, preferences, new tab and address bar. Thank you to Greg for taking most of those on.

Community

  • Lots of Outreachy applicants are showing up! Keep your eyes peeled for Bugzilla comments asking to be assigned to good-first-bugs. Respond ASAP to questions from applicants.

    • good-first-bug in Bugzilla keyword

    • [lang=js] or [lang=css] [lang=html] in the whiteboard

    • Set yourself in the Mentor field

This week I learned

  • [gijs] Someone I spoke to didn’t know this one neat trick: on treeherder, you can filter jobs by test paths! Click the funnel icon on the top right, then in the dropdown on the left select “test path” and put in a path to a directory or file, and click the “add” button. Treeherder will hide all the jobs not running tests there. Useful when looking at treeherder to see when particular breakage was introduced, or which jobs run which tests. The URL will also reflect this selection.
