How do I disable tab seperator when selecting text?

D3Qn | Last updated: Mar 20, 2023 02:26PM UTC

Hi there, this one is a bit hard to describe. When selecting text or clicking into the text when using e.g., repeater the UI automatically adds spacing for better readability. For example: cmd=<script>alert("asdf")</script> Becomes: cmd=<script>alert("asdf")</script>

Posted by accident before finishing and there is no edit button <.< For example: cmd=<script>alert("asdf")</script> Becomes: cmd=<script>alert("as df")</script> when I put my courser in front of the d. How do I disable this behavior? Its annoying as hell

Hi Thanks for getting in touch. We've just been testing this here and don't see the same behavior. Can you send an email to support@portswigger.net with some more information about your installation and the behavior so we can take a closer look, please? - Do you only see this issue with this kind of text, or does it happen with all requests you try and edit? - Which version of Burp are you using? - Does your display use any custom scaling? Which font and size do you have configured for the message editor? - Can you also send us the output from Help -> Diagnostics for your installation of Burp?

Hi, thanks for the answer. I just sent the mail. I will post here when a solution is found. Likely culprit seems to be following code to make Burp Suite properly scale its UI to my 4k displays. export _JAVA_OPTIONS="-Dsun.java2d.uiScale=2"

Thanks for the update. We've just replied to your email to check a few more details regarding your OS and whether you also have scaling options set at OS level.
