Internal browser forces HTTPS after update

Amy | Last updated: Oct 26, 2023 01:53PM UTC

Hello! I am using the internal browser in Burp Suite, and after updating the community edition to version 2023.10.3.1 the browser forces HTTPS when I try to go to a HTTP site, and I get the error message "Unsupported or unrecognized SSL message" This worked yesterday before the update. After googling I found some posts saying that this was a issue with Chromium in previous versions. Since this update upgraded the Chromium, I think this might be the same issue? I have tried enabling and disabling "Convert HTTPS links to HTTP" without success. I have also tried using intercepter and dropping the first HTTPS request, also without success. Any help would be appreciated!

Hi If you go to Settings > Tools > Burp's browser > Browser data and either 'Clear all browser data from the browser data folder or change the folder used for browser data, does the issue persist?
