[1] Firefox supports only single-line flexbox until Firefox 27. To activate flexbox support, for Firefox 18 and 19, the user has to change the about:config preference layout.css.flexbox.enabled to true.

In addition to the unprefixed support, Gecko 48.0 (Firefox 48.0 / Thunderbird 48.0 / SeaMonkey 2.45) added support for a -webkit prefixed version of the property for web compatibility reasons behind the preference layout.css.prefixes.webkit, defaulting to false. Since Gecko 49.0 (Firefox 49.0 / Thunderbird 49.0 / SeaMonkey 2.46) the preference defaults to true.

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