Disable datepicker
The new datepicker for date inputs that has been enabled since Firefox 57 conflicts with solutions (like jqueryui or boostrap) used to overcome the lack there of previous to FF57. There needs to a ccs option to disable or "hide" Firefox's new datepicker just like chrome does. Setting the -moz-appearance has no effect.

Right, it conflicts with old jquery UI. You have to hide the datepicker in about:config, it is dom.forms.datetime.
Or, which is better, unify your jquery.

Isn't about:config a per browser setting? This solution only solves it for a single person viewing; not for a public website. Removing the previous datepickers is not a viable option especially with all the additional features not provided by the Firefox datepicker.
