These settings let you control the appearance of Burp's user interface. You can configure the font size that is used throughout the UI (except for display of HTTP messages), and also the Java look-and-feel. Changes to these settings will take effect when Burp is restarted.
How to enable dark mode in Burp Suite
To enable Burp Suite's dark mode, go to the "User settings" > "Display" tap. Under "User Interface", from the "Look-and-feel" drop-down menu, select "Darcula". These changes will be applied the next time you launch Burp Suite.
HTTP message display
These settings let you control how HTTP messages are displayed within the HTTP message editor. You can configure the font face and point size, and whether font smoothing is used. You can choose from a list of all monospaced fonts found on your system.
The following additional options are available:
These settings control how Burp handles different character sets when displaying raw HTTP messages. The available options are:
- Recognize the character set of each message automatically, based on the message headers. This is the default option, and lets you work concurrently on messages that use different character sets.
- Use the platform default character set for all messages.
- Display messages as raw bytes (using ASCII encoding), without processing any extended characters.
- Use a specific character set for all messages.
HTTP headers are always displayed in raw form - the charset encoding options only apply to the message body.
Note that the glyphs required for some 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 tab within the HTTP message editor displays HTML content approximately as it would appear in your browser. This option controls whether Burp will make any additional HTTP requests that are required to fully render HTML content (for example, for embedded images). Use of this option involves a trade-off between the speed and the quality of HTML rendering, and whether you wish to avoid making any further requests to the target application.
