We're probably going to want to reimplement flexbox as it gets standardized; I don't see this happening before we do that.

Attachment: Testcase adapted from corresponding webkit bug

The testcase uses an imaginary experimental property -moz-box-lines.

I realize Bugzilla is not the place to evangelize. However seeing that things like rounded corners and shadows, though also experimental, are widely implemented I think it's fair to say that "CSS3 Flexboxes" have not gotten the attention it warrants,  even though its significance can hardly be overstated. That is, if you're a web developer who's has had to put up with  the madness of hacking up layouts with floats and absolute positioning! In order to build non-super-trivial layouts sanely, quickly and easily flexboxes are the way to go!

Box-lines: multiple is the missing piece, because it's absence breaks usability (think small screens).

Flexie a JS polyfill that makes flexboxes usable across browsers today, which for me presents nothing less than a revolution in the way I code web layouts.

As a frontend web dev I'll argue that Flexboxes are the most important module of CSS3! Thanks, and I hope you'll excuse may non-implementation oriented comment...

This bug is invalid with the new css3-flexbox draft.

[Minh Nguyễn]

The new draft has "flex-wrap: wrap", which corresponds to the old "box-lines: multiple". Firefox 18 with layout.css.flexbox.enabled set doesn't seem to recognize the "-moz-flex-wrap" property at all.
