downloading knime extensions manualy


as the firewall of my company does not allow me to connect to the knime server I'm looking for ways to get extensions or download certain extension i.e when I load a workflow some one else made and find a missing node. Is it possible to search and find such nodes manually on the knime website?

Like downloading it in a zip file or something ?


There is a download update site link on this page:
