-//   opened in the browser by extracting the right URL for the file.
-// - If the file is a CRX file, the CRX file will be installed.
-// - If the file is on Drive, the file will be downloaded from Drive as
-//   needed.
-//
-// Returns false if failed to open. This happens if the file type is unknown.
