Foxified allows users to emulate Firefox extensions in Chrome, Opera, and other Chromium-based browsers. With features like an Emulation Sandbox, Firefox addons are served in a sandboxed unique origin for enhanced security. The WebExtension API provided by Foxified polyfills most browser and Chrome APIs, including XHR and webextension API, ensuring compatibility with a wide range of extensions.

For added security, Foxified offers an extra layer of protection by making all permissions optional and requesting them upon plugin installation. It's important to note that not all Firefox extensions are currently supported, as Foxified focuses on stable APIs. Additionally, Foxified prioritizes user privacy by not including analytics or collecting any user data, although caution is advised when installing guest extensions.
