title: How can I close a browser tab knowing the process ID?
body: <p>I have a process that adds tabs to Vivaldi (or any browser): one to an external url and one to a local html file. I am able to identify the process IDs associated with each tab.</p>
  <p>I want to be able to close the tabs. I have tried <em>kill &lt;id&gt;</em>. That clears the page of the local file, but the tab is still there and can be reloaded if I refresh the page. <em>kill</em> has no effect on the tab associated with the external url.</p>
  <p>Is there a way to do this?</p>
