It seems like it's not really a problem with Datepicker, but with md-input-container instead, take a look here: https://jsbin.com/zilisazade/edit?html,js,output - 2nd input (not nested inside md-input-container) displays date in every browser, and after small research I found this issue #1409.

So it looks like for some reason FF/IE isn't handling this CSS rule properly - https://github.com/angular/material/blob/master/src/components/input/input.scss#L151, but everything works as expected if you divide this rule into 2 chunks (let's say general & webkit specified), just like that:

&:not( .md-input-has-value ) input:not( :focus ) {
  color: transparent;
}

&:not( .md-input-has-value ) input:not( :focus )::-webkit-datetime-edit-ampm-field,
&:not( .md-input-has-value ) input:not( :focus )::-webkit-datetime-edit-day-field,
&:not( .md-input-has-value ) input:not( :focus )::-webkit-datetime-edit-hour-field,
&:not( .md-input-has-value ) input:not( :focus )::-webkit-datetime-edit-millisecond-field,
&:not( .md-input-has-value ) input:not( :focus )::-webkit-datetime-edit-minute-field,
&:not( .md-input-has-value ) input:not( :focus )::-webkit-datetime-edit-month-field,
&:not( .md-input-has-value ) input:not( :focus )::-webkit-datetime-edit-second-field,
&:not( .md-input-has-value ) input:not( :focus )::-webkit-datetime-edit-week-field,
&:not( .md-input-has-value ) input:not( :focus )::-webkit-datetime-edit-year-field,
&:not( .md-input-has-value ) input:not( :focus )::-webkit-datetime-edit-text {
  color: transparent;
}

But I'm not sure if that's a good solution.

I'm not sure if this is still an issue for others but I found this solution worked in both chrome and firefox

input:not( :focus ) { color: transparent; } input:valid { color: inherit; }
