Project Updates

Add-ons / Web Extensions

WebExtensions Framework

• Enabled nightly-only rejection on invalid cookies created through the cookies WebExtensions API – Bug 1976197
  • NOTE: this behavior is currently only enabled in Nightly builds, Bug 1976509 is tracking enabling it on all channels

WebExtension APIs

• • A new onUserSettingsChanged API event has been added to the action API namespace to allow the extensions to be notified when their toolbar button is pinned/unpinned from the toolbar – Bug 1828220

• Thanks to Gregory Pappas for contributing this new API enhancement!

DevTools

• Manuel Bucher [:manuel] added MDN link in Netmonitor for Alt-Svc and Alt-Used headers (#1977374)
• :glob ✱ fixed browser_devices.js test (#1975963)
• Holger Benl [:hbenl] fixed an issue in Responsive Design Mode touch simulation where we would trigger too many events on pages with same-origin iframes (#1973691)
• Alexandre Poirot [:ochameau] fixed an issue in the Netmonitor where Search results would collapsed when new requests were added to the main list (#1975441)

WebDriver BiDi

• Thanks to :biyul for reverting a workaround used to avoid incorrect properties in our network events, but no longer needed thanks to improvements on Necko side.
• Henrik refactored all the Marionette test files for chrome scope to no longer ship with Firefox. This also removed the last shipped DTD file, which allowed further cleanup. The chrome test file for reftests was updated to include necessary CSP directives.
• Thanks to this, Henrik could finally remove the Marionette exceptions for CSPs.
• :biyul also removed support for “localize_entity” from localization module, which was only useful when used against DTD files, and therefore no longer needed.
• Henrik cleaned up remaining code for support of FTP proxy in WebDriver capabilities. This feature has not been supported since Firefox 90.
• Sasha added an API to BrowsingContext to override locale in JS APIs and a new “emulation.setLocaleOverride” WebDriver BiDi command, which utilizes the new BrowsingContext property under the hood.
• Sasha updated the Marionette command for adding cookies to throw an error when a cookie has with “sameSite=none” and “secure=false” values.
• Also, Sasha improved setting a proxy with “browsingContext.createUserContext”: added support host patterns like “.mozilla.org” in “noProxy” property and fixed a bug when setting an http proxy wouldn’t let to navigate to HTTPS URLs.

Lint, Docs and Workflow

• Standard8 added a linter to check that licenses are acceptable for the node modules included via the top-level and eslint-plugin-mozilla package.json files.
  • This will be expanded to more package.json files in future.
  • Linter Docs
  • Runbook

Profile Management
