Chrome and Firefox provide users with options to manage registered Service Workers in the browser, including options to remove Service Workers from the browser.
Service Workers are an up and coming feature supported by most modern browsers that enable sites and services to interact with the browser without having to be open in it.
Web browsers are not designed currently to prompt users all the time when Service Workers are registered in the browser. This happens as a background process most of the time currently.
The Service Worker is registered either automatically, or after the user accepts a prompt. Pinterest is a website that registers one automatically when the site is visited in Chrome or Firefox.
This is not made clear to the user as it happens in the background.
