Issues: Find and fix problems

Published on

The Issues tab in Chrome DevTools reduces the notification fatigue and clutter of the Console. Use it to find solutions to problems detected by the browser, such as cookie issues and mixed content.

In Chrome 84, the Issues tab supports three types of issue:

Future versions of Chrome will support more issue types.

Open the Issues tab

  1. Visit a page with issues to fix, such as samesite-sandbox.glitch.me.

  2. Open DevTools.

  3. Click the Go to Issues button in the yellow warning bar.

  4. Once you're on the Issues tab, click the Reload page button if necessary.

    You'll notice that issues reported in the Console (such as the cookie warnings here) are quite hard to understand. It's not clear what needs to be done to fix the issues reported.

View items in the Issues tab

The Issues tab presents warnings from the browser in a structured, aggregated, and actionable way.

  1. Click an item in the Issues tab to get guidance on how to fix the issue and find affected resources.

    Each item has four components:

    • A headline describing the issue.
    • A description providing the context and the solution.
    • An AFFECTED RESOURCES section that links to resources within the appropriate DevTools context, such as the Network panel.
    • Links to further guidance.
  2. Click on AFFECTED RESOURCES items to view details. In this example, there is one cookie and one request affected.
