Reporting bugs

Bug hunting is not difficult if you know how.

How to report a bug

We are using GitHub Issues for our public bugs. We keep a close eye on this and try to make it clear when we have an internal fix in progress. Before filing a new task, try to make sure your problem doesn't already exist.

If you found a bug, please report it, as far as possible including:

  • a detailed explanation of steps to reproduce the error.
  • a browser and the browser version used.
  • a dev tools console exception stack trace (if it is available).

Consider sending us an email first at if you discovered a bug that you'd prefer to discuss in confidence (such as a security bug).

We don't have formal bug bounty program for security reports; this is an open source application and your contribution will be recognized in the changelog.
