ZendeskAutoRefresh oleh Luca Brian

This add-on let's you automatically refresh the Zendesk ticket page without refreshing the whole tab which removes filters etc.
You can set the refresh interval when clicking on the add-on icon in the browser.

You can find the code on Github so it can be validated by IT departments to be allowed in companies with strict security requirements.
