I updated my browser, and without any warning, most of my user-scripts are broken. This is mostly because, suddenly, I cannot access properties from the page's global window objects that were defined by page scripts (native properties are available).
This prevents me from overriding functions, reading global variables etc. The stuff that people usually do with user-scripts.
The question therefore is, how can I reverse this, apart from downgrading to old Firefox?
How to access and/or change global scope from user scripts in Greasemonkey 4?
