How to Install Firefox on Your Synology NAS

Firefox Browser, also known as Mozilla Firefox or simply Firefox, is a free and open-source web browser developed by Mozilla. Firefox uses the Gecko layout engine to render web pages, which implements current and anticipated web standards. Firefox is more than a browser. It’s a whole family of products designed to keep you safer and smarter online. In this step by step guide I will show you how to install Firefox on your Synology NAS using Docker.
