How to generate a HAR file in Chrome

Start by opening Google Chrome.

  • In Chrome, go to the page within our application where you are experiencing trouble

  • Select the Chrome menu (⋮) at the top-right of your browser window, then select Tools > Developer Tools.

  • The Developer Tools will open as a docked panel at the side or bottom of Chrome. Click on the Network tab.

  • Select the option Preserve log (at the top of the panel)

  • The recording should autostart and you will see a red circle at the top left of the Network tab. If not, click the black circle, to start recording activity in your browser.

  • Refresh the web page you are on. The goal is to reproduce the problem you've been experiencing while Google Chrome is recording activity.

  • Once you've encountered the problem successfully while recording, right-click within the Network tab and click Save as HAR with Content to save a copy of the activity that you recorded.

  • Save the HAR file somewhere convenient.

You're done! Please attach the HAR file to an email or share it on slack.

How to generate a HAR file in Firefox

Start by opening Firefox.

  • In Firefox, go to the page within our application where you are experiencing trouble.

  • Select the Firefox menu (Three horizontal parallel lines) at the top-right of your browser window, then select Developer > Network.

  • The Developer Network Tools will open as a docked panel at the side or bottom of Firefox. Click on the Network tab.

  • The recording will autostart once you start performing actions in the browser.

  • Refresh the web page you are on. The goal is to reproduce the problem you've been experiencing while Firefox is recording activity.

  • Once you have reproduced the issue and you see that all of the actions have been generated in the Developer Network Panel (should just take a few seconds), right click anywhere under the "File" column and click on "Save all as Har" > Save the file somewhere convenient.

  • Save the HAR file somewhere convenient.

You're done! Please attach the HAR file to an email or share it on slack.
