In addition to Ben's comments,I think your issue is you're trying to load your site from a file:// url,not a webserver.
By default,Firefox doesn't allow file:// urls to work with JavaScript. You have to enable it.
在火狐网址栏输入：
about:config
security.fileuri.strict_origin_policy needs to be set to false
To be able to serve from the filesystem (no webserver).
