I am using the Pure Grids of PureCSS. I have a pure-g with three pure-u-1-3, containing a few paragraphs. The problem is that there is a difference in display between Chrome/IE and Firefox when one of the units is longer than the others.

I have tried to use jQuery to calculate the highest pure-u-1-3 and setting the rest to this height. But it didn't work out as expected, since this grid has to be responsive as well (using pure-g-r)
Does anybody know how to make Firefox produce the same output?
As purecss has fixed the problem (v0.6) by implementing it in every browser, this answer is obsolete.
Your problem is that PureCSS is using -ms-display: flex in Internet Explorer and -webkit-display: flex in Webkit Browsers. Opera, Firefox and (obviously) older IEs don't get this solution.
To get it working in Firefox (20+) and Opera you could apply the following in your stylesheet:
.pure-g-r {
display: flex;
}
