How to generate a HAR and log file in Chrome, Microsoft Edge, Firefox and Safari

When troubleshooting issues in MediRecords, it is often essential to see exactly how your browser is interacting with the system. A HAR (HTTP Archive) file captures a detailed log of all network requests and responses between your browser and the website, including timing, errors, and background processes. This information allows the support team to pinpoint the cause of technical issues that may not be visible on the surface, such as failed requests, slow loading times, or data not transmitting correctly.

By generating and sharing a HAR file, along with any console logs, you provide our team with a clear picture of what happened during the issue. This significantly speeds up the diagnostic process and helps us resolve your support request more efficiently. The steps below outline how to generate a HAR file and log across the most common browsers: Chrome, Edge, Firefox, and Safari.
