I used to use "Disable JavaScript" with an uncooperative webpage, especially one disabling things like right-click with JavaScript or popping up ads/modals every 5 seconds. Apple removed it and I can't find it anywhere now. Why???
It's annoying that it's no longer a dedicated menu item because that means we can no longer bind a key to it using System Settings > Keyboard > Keyboard Shortcuts > App Shortcuts. I used to do this for both JS and CSS.
