Calendar date picker on system_usermanager.php only works in Chrome
The calendar date picker on system_usermanager.php doesn't show up in any browser other than Chrome from the looks of it. Confirmed Safari and Firefox on OS X and Linux just have a text box for "Expiration date" without the format hint and control for picking the date. Screenshots in this post.

It's probably similar to this: https://forum.pfsense.org/index.php?topic=112358.0.
It could be replaced with the jquery datepicker.
