Lint, Docs and Workflow
:Mossop, :Gijs and Standard8 met and discussed the remaining rules (and a few others) that are recommended by ESLint but that we haven't enabled yet.
no-useless-escape has been turned off, as the work to enable it would have been significant, and it doesn't catch any real errors.
getter-return, no-constant-condition and no-case-declarations have all been turned on.
object-shorthand has been enabled on the debugger code.
no-console is to be enabled soon for production code.
no-shadow is also on the list to enable for production code (with various exceptions)
no-use-before-define is also likely to be enabled with a limited set of options
- :Mossop is working on enabling argument linting from no-unused-vars. 47 patches have already landed, 11 to go!
- :Gijs has enabled a new rule to prevent comparison or assignments within ok() assertions in tests.
- The ESLint configuration has been changed so that all .jsx files are now assumed to be ES modules.
- Pocket's files that are modules have been renamed to use .mjs extensions
Migration Improvements
We’ve started early investigations on a profile backup feature. This feature will, in theory, allow users to create backups of their user profile in an archive on the local file system. We’re still very early days here, but we have a meta bug here that people can follow along with.
New Tab Page
- We’re in the early phases of building out an experiment that lets people set wallpapers on about:home/about:newtab. Stay tuned!
Performance Tools (aka Firefox Profiler)
