This new context menu entry will be available only when the advanced setting `filterAuthorMode` is set to `true`. See: https://github.com/gorhill/uBlock/wiki/Advanced-settings#filterauthormode The purpose is for filter list maintainers to easily access the source code of web pages when investigating filter issues, without having to necessarily go through the logger. Additionally an input field to enter URL directly has been added to the code viewer for convenience.
