Is Stylus safe?

Clean risk

This extension applies custom CSS styles and themes to redesign websites you visit.

Stylus lets you install userstyles from popular online repositories or from .user.css and .user.styl URLs, and it also lets you create, edit, and manage your own stylesheets. It includes backup for installed styles, automatic style updates, UI customization options, and optional code validators. Its website access permission is used to add style elements to pages you visit.

Shared hosts - 11 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
