Currently, only Chrome and Firefox can access the HAR feature by default. Other browsers either require a browser extension or cannot generate a HAR. When installing a browser extension, follow the instructions from the extension provider.

▼ In Chrome

In a browser page, right-click anywhere and select Inspect Element.

The developer tools either appear at the bottom or left side of the browser. Click the Network tab.
