How do I generate a HAR file from a browser?
Follow these steps to generate a HAR file from the browser where you are facing an issue:

1. Open the page you find slow or having an issue.
2. Make sure you have activated Open > Chrome > Developer Tools > Network.
3. Clear all the existing requests.
4. Reload the page for performance issues. For any other errors do not click refresh on the browser but perform the action that will send an Ajax request in the Network console. Once you see one entry for the Network, go to step 5. 
   1. Note: You should see a series of network requests.
5. Right-click inside the Network panel and Save as HAR with Content.

Note:

• HAR files can have sensitive information - so care should be taken to respect the privacy policy.  
• HAR Viewer can be used to analyze data. So ensure the HAR Viewer is not sending out the information to any 3rd party website for analysis.
