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.

From the application menu, select Tools > Web Developer > Network or press Ctrl+Shift+I (Windows/Linux) or Cmd+Option+I (OS X).
Browse to the URL that causes issues.
After duplicating the issue, right-click and choose Save All As HAR.

Internet Explorer cannot build HAR files, but a similar functionality is described on Microsoft Developer Network.

Navigate to Developer tools (use F12 as a shortcut) and select the Network tab.
Browse to the URL that causes issues.
After duplicating the issue, click on Export as HAR followed by Save As…

▼ In Safari

In Safari, ensure a Develop menu appears at the top of the browser window. Otherwise, go to Safari > Preferences > Advanced and select Show Develop Menu in menu bar
Navigate to Develop > Show Web Inspector.

Web Inspector is not available until you browse a page other than Safari’s starting page.

Browse to the URL that causes issues.
Ctrl + click on a resource within Web Inspector and click Export HAR.
