Javascript Not rendering

Shaya | Last updated: Aug 17, 2021 08:34AM UTC

Hello Team, When proxying through burp the webpage isn't rendering any of the javascript. This results in most of the significant features of the page remaining unloaded. When I remove the proxy everything loads fine. Webapp is a *.firebaseapp.com Tested using the burp-built-in-browser as well as firefox with foxyproxy.

Hi Shaya, We have replied to your email regarding the same issue. For anyone else who sees this behavior, please share the information below with support@portswigger.net - Screenshots of the Developer tools > Console, and Network tabs when the issue occurs. Please ensure that the protocol column is visible in the Network tab - Is the issue that some resources are failing to load? What response are you seeing in the browser and Burp? - Which version of Burp are you using? - Have you tried enabling JavaScript-driven redirection under Project options > HTTP?

HI! I have got the same problem. No JS scripts render on the page. Has this issue been solved yet?

Hello, I have a similar problem when testing a website using Firefox with FoxyProxy, and using Burp Suite Community Edition. Some of the errors received are "jQuery is not defined", "$ is not defined". Can you help me solve this issue?
