Bug Fixing in DevTools

Every quarter the DevTools team devotes a few people to bug fixing and polish bugs that are beyond the team goals.

The bugs in this effort are meant to be the most important polish/paper cut type bugs in each component. They should not include new features. The focus here is on improving quality and polish in our existing feature set.

Things to be found in these lists:

  • actual issues that prevent using the tool easily
  • small broken things that prevent a good UX

This page serves as a dashboard for finding those bugs across various issue trackers like Bugzilla and GitHub.
