Userscripts
Userscripts is an open-source Safari extension for running your own JavaScript and CSS on selected websites.
Choose it when you understand the scripts and styles you plan to enable.
Redirects, page changes and custom styling can automate narrow browser preferences.
Keep in mind: Arbitrary scripts can change pages or access their content; it is not a ready-made guarantee of safe blocking or privacy.
