title: How do I run a local Unity WebGL (file:// url) build?
body: <p>Multiple browsers (Chrome, Firefox, Internet Explorer) give the following error when trying to open a local Unity WebGL build:</p>
  <blockquote>
  <p>It seems your browser does not support running Unity WebGL content from file:// urls. Please upload it to an http server, or try a different browser.</p>
  </blockquote>
  <p>Microsoft Edge is able to run it, but I would like to know if there are any settings that can be changed to get it to run on Chrome/Firefox/other browsers.</p>
