claims that Firefox fully supports fit-content.

CanIUse says it doesn't:
<https://developer.mozilla.org/en-US/docs/Web/CSS/fit-content>

And Dev Tools in Firefox 87 says that "height: fit-content;" has an
invalid property value.

I have a parent DIV that contains a number of vertically aligned DIVs.
The parent DIV is a relatively positioned element, It has "display:
flex;" and is a item in a grid.

I run some calculations on the parent DIV so I need it's height to match
the overall height of the nested DIVs. How can I get the two to match?

Dr DuckDuckGo (DDDG) suggested I use -moz-fit-content and that seems to
get Firefox to behave as other browsers using fit-content.

the yellow background - indicates support with preix … hover over or
click on browser will produce a popup revealing more support info

accessibility issue perhaps

The information was there on MDN and CanIUse … just over looked and
hidden.

Oh, this is the first time I've ever clicked the down arrow.

On my computer the background colour is green (indicating 'full
support') but I now realise what the little square with the dash in it
means there's some relevant information available on hover.

Yes, I missed it both times.
