Viewing HTTP Headers Using Browser Developer Tools Firefox

In Firefox, you can view HTTP headers using the browser's developer tools. To do this, open the developer tools by pressing F12 or right-clicking on a webpage and selecting Inspect.

The Network tab is where you'll find the HTTP headers. This tab displays a list of all the resources loaded by the webpage, including images, scripts, and stylesheets.

Clicking on a resource in the list will display its details, including the HTTP headers. The headers are listed in a tab called Request Headers or Response Headers, depending on whether you're viewing the request or response.

You can also use the Console tab to view HTTP headers, but the Network tab is generally more useful for this purpose.
