A .HAR file is a log that records the interaction between a web browser and a website. These interactions consist of each resource on these websites being loaded and the log (.HAR) measures the time it takes each resource to load. The .HAR helps identify if a particular resource is taking longer to load than others, which might cause performance issues.
To obtain the .HAR file from your browser, follow the instructions below.
