Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience surfing the web. In this step by step guide I will show you how to install Chromium on your Synology NAS with Docker & Portainer. Note: You can also install Ungoogled Chromium, Opera, Firefox, LibreWolf, Tor Browser, or Mullvad Browser to surf the web using your NAS.

💡Note: This guide works perfectly with the latest version of Chromium
