Burp Chromium Browser Always Upgrades to TLS

Problem

In the browser, you enter http://domain.tld or http://10.10.10.10 for example. If you're working on a CTF or a project where HTTP over TLS is not enabled, then the default setting of the Burp Chromium browser is to try and upgrade the connection to https://.

Solution

Settings menu > Privacy and security > Security then under the Advanced section, disable the setting to Always use secure connections.
