Globals not defined on Greasemonkey

[rossjrw]

When using Greasemonkey, globals (e.g. OZONE) are not defined due to its sandboxing behaviour.

@emmiegit suggested moving code into the browser context by adding it to a script tag, suggested https://github.com/scpwiki/user-info-script/blob/main/user-info.user.js as example. I am a bit confused on why this works, but that's why I'm writing an issue instead of just doing it

Simple replace of window for unsafeWindow does not work - no permission to access properties of DOM objects, userscript sandbox acts like a cross domain iframe

@emmiegit clarified: in that example, UINFO is an object in the page context just like OZONE. The userscript cannot access UINFO just like it cannot access OZONE. A UINFO method is called via the onclick handler of a button element that it creates. The onclick handler runs on the page in the same context as the script, it cannot access anything from the userscript and vice versa.
