Multiple browsers (Chrome, Firefox, Internet Explorer) give the following error when trying to open a local Unity WebGL build:

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.

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.
