Desktop Integrations

ESMification status

• Please consider migrating your components if you haven't already. Don't forget actors as well.

• ESMified status:

  • browser: 46.4%

  • toolkit: 31.62%

  • Total: 43.6% (up from 41.3%)

• #esmification on Matrix
• Migration Document (with a walkthrough!)

Lint, Docs and Workflow

(no voice update this week)

• A new rule has been added to disallow the single-argument form of Cu.reportError. console.error should be used instead.

  • There is a meta bug for the work to remove (or replace) Cu.reportError completely.

  • Replacing the two argument form will come later as it still needs some investigation.

Migration Improvements (CalState LA Project)

• Steven landed a patch that lets us open up the migration dialog in a tab modal
• Evan landed a patch that adds a new Opera GX migrator
• mconley added some infrastructure for a new migrator wizard, and also wrote a bunch of documentation for the students who are going to be working on it
• The students are now on exam / winter break and will hit the ground running again in late January.

Performance Tools (aka Firefox Profiler)

• Made searching in markers more generic. Now any property can be a searchable property, the gecko engineers can now change this themselves without changing the frontend. (PR #4352, Bug 1803751)
• Landed some changes in the category colors (more contrast, brown is now really brown, added a new magenta color).
• Changed the treeherder performance regression template to output the before and after profile links for each regression (PR #7588)
  

New “Performance Profiles” column in performance regressions
