The Problem:
In a full-size app layout (100% width, 100% height) using flexbox with overflow, the scrollbars do not display for overflow-y in Firefox, IE, or Edge. They do display properly in Chrome. Rather than having a vertical scrollbar in FF/IE/Edge on the element, the scrollbar is applied to the entire page.
What I've Tried:
I've tried adding, as mentioned in several other SO answers, to add min-height: 0; to the flex elements / parents. I haven't been able to get this solution to work, but perhaps I am doing something wrong.

It looks like the problem stems from this section of your code:
.canvas-wrapper {
overflow: scroll;
}
You want this element to have scrollbars. However, the element has no defined height.
From MDN:
In order for
overflowto have an effect, the block-level container must have either a set height (heightormax-height) orwhite-spaceset tonowrap.
Chrome doesn't seem to care about the height requirement. The other browsers do.
This should be enough to make it work across browsers:
.canvas-wrapper {
overflow: scroll;
flex: 1 0 1px;
}
html {
height: 100%;
}
.flex-grow {
flex: 1;
}
.canvas-wrapper {
overflow: scroll;
flex: 1 0 1px; /* NEW */
}
.canvas {
width: 3000px;
height: 3000px;
}<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" rel="stylesheet"/>
<body class="h-100">
<div class="h-100 container-fluid d-flex flex-column">
<div class="row bg-warning">
<div class="col-12 py-4">Top Bar</div>
</div>
<div class="row no-gutter flex-grow">
<div class="col-9 px-0 d-flex flex-column">
<div class="canvas-wrapper">
<div class="canvas bg-success">
Canvas
</div>
</div>
<div class="bg-danger py-3">
Canvas Footer
</div>
</div>
<div class="col-3 bg-primary">

</div>
</div>
<div class="row bg-warning">
<div class="col-12 py-2">Overall Footer</div>
</div>
</div>
</body>When using percent for height on element, all its ascendants also need a height set, and if all will have percent, one need to set it all the way up to the html/body.
When combined with Flexbox this can get really tricky to solve, as when one need to set height: 100% on all ascendants, other unwanted render issues can cause the layout to break.
Here is one solution, which work perfect cross browser, where an extra wrapper, canvas-fix, for the canvas is added, and then with position: absolute we can make this work.
