The userChrome file which I just now created for live editing and creating a mod, has this generated content and if I add anything at the bottom it works but if I restart the browser it gets reset back to this generated css.
For context the userChrome.css file was not there in the profile folder I created it and now I can't use it. I followed the steps from https://docs.zen-browser.app/guides/live-editing.
Zen browser version: 1.7.4b
OS: Windows 11
