run user script on chrome://settings and similar urls

Question

Why doesn't tampermonkey work on urls such as chrome://history/ or chrome://settings/? Any way to run an user script on this pages as well?

Answer 1

Unfortunately, this isn't possible, because the chrome scheme (chrome://) isn't supported in @match's abilities.

UserScripts also use Chrome's match spec, so a Chrome extension to do that wouldn't work either.

From the linked spec:

Host permissions and content script matching are based on a set of URLs defined by match patterns. A match pattern is essentially a URL that begins with a permitted scheme (http, https, file, or ftp, and that can contain '*' characters).
