Linebreaker
Summary: PortSwigger lists Linebreaker, a Burp Suite extension by Ads Dawson at version 1.0.0 and last updated 23 September 2025, which renders escaped newline sequences (\n) as actual line breaks in a dedicated message editor tab. The tool is meant to improve analysis and modification of request and response data containing formatted content, and PortSwigger notes that extensions are written by third-party users and carry no warranty of quality or usefulness.
What you should know: This is a third-party BApp with no warranty from PortSwigger, so anyone adding it to Burp is trusting code outside the vendor's own review to handle live request and response data.
