       | On Firefox, after bypassing the ominous warnings, when I tried to
       | create a new project and choose a directory to save the project
       | files, I get                 > Directory picker is not supported
       | in this browser. Please use a modern browser like Chrome or Edge.
       | 
       | While I appreciate the early warning, so that the user doesn't
       | spend too much effort only to later realize that they can't save
       | their files to disk, I don't appreciate the implicit labeling of
       | Firefox as not being a "modern" browser.
       | 
       | If you're developing a web app with APIs only available in
       | certain browsers, just say/admit so.
