问题描述
根据， display：flex 属性应该在firefox 21中没有任何前缀。但是，即使我在 -moz -
According to this article, the display:flex property should work without any prefix in firefox 21. But, even if I use -moz- before the value, it is not being recognized by the HTML parser.
我尝试卸载firefox 20并重新安装firefox 21最近希望它能工作，但它不工作。
I tried uninstalling firefox 20 and reinstalling firefox 21 recently hoping it would work, but it doesn't.

推荐答案
display：flex 目前仅支持Firefox中的运行时标志。
display: flex is currently only supported behind a runtime flag in Firefox.
about：config在url字段中，搜索flexbox并将其设置为true。
To enable it, enter about:config in the url field, search for flexbox, and set it to true.
它默认情况下在Firefox Nightly中启用，因为它是一个不稳定的版本。
It is enabled by default in Firefox Nightly, as it is a non-stable version.
这是因为默认情况下在Firefox 22中启用，只要该功能可以发货。
It is due to be enabled by default in Firefox 22, providing the feature is ready to ship.
