[1] Firefox supports only single-line flexbox until Firefox 28. To activate flexbox support, for Firefox 18 and 19, the user has to change the about:config preference "layout.css.flexbox.enabled" to true.

[2] Before Firefox 32, Gecko wasn't able to animate values starting or stopping at 0.

[3] Internet Explorer 10 uses 0 instead of 1 as the initial value for the flex-shrink property. A workaround is to always set an explicit value for flex-shrink. See Flexbug #6 for more info.
