The Message editor settings page is located under User interface in the Settings dialog.
You can edit how the message editor is displayed:
The Message editor settings are user settings. They apply to all installations of Burp on your machine.
The Message editor request views and Message editor response views settings enable you to adjust the views of the message content in the message editor. Each view is displayed in an individual tab, and provides the same functionality as the widgets in the Inspector.
For each view option, you can:
To reorder the list of views, use the Up and Down buttons.
In read-only contexts, such as the proxy history, the message editor only displays the selected views if the message contains appropriate content. For example, you won't see the Cookies tab unless the request contains one or more cookies.
In editable contexts, such as in Burp Repeater, the message editor displays all views. This gives you the option to add items even if none were included in the original request.
These settings enable you to control how HTTP messages are displayed within the HTTP message editor. You can configure the following:
These settings control how Burp handles character sets when it displays raw HTTP messages. The available settings are:
HTTP headers are always displayed in raw form. The charset encoding options only apply to the message body.
Some of the glyphs required for certain character sets are not supported by all fonts. If you need to use an extended or unusual character set, you should first try a system font such as Courier New or Dialog.
The Render view within the HTTP message editor displays HTML content approximately as it would appear in your browser. This setting controls whether Burp can make additional HTTP requests to fully render HTML content (for example, to display embedded images).
Select this setting to increase the quality of Burp's HTML rendering at the expense of some speed. This setting increases the overall number of requests that Burp makes to the target application.
The HTTP Message search settings control the search bar at the bottom of the message editor window. By default, none of these settings are enabled:
Use this setting to hide specified HTTP headers in the Pretty tab of the message editor by default. This enables you to reduce clutter, helping you focus on more valuable information.
To automatically hide HTTP headers across Burp, select Hide the following headers by default. Burp hides the defined list of headers. You can customize this list in the following ways:
