使用条件注释很容易针对Internet Explorer浏览器特定的CSS规则:
<!--[if IE 6]>
...include IE6-specific stylesheet here...
<![endif]-->
有时是Gecko引擎(Firefox)行为不当。将CSS规则只针对Firefox而不是其他浏览器的最佳方法是什么?也就是说，不仅Internet Explorer应该忽略仅限于firefox的规则，WebKit和Opera也应该忽略。
注:我正在寻找一个“干净”的解决方案。在我看来，使用JavaScript浏览器嗅探器向我的HTML中添加一个“firefox”类并不算干净。我更希望看到一些依赖于浏览器功能的东西，就像条件注释只对IE来说是“特殊的”……

现在，Firefox Quantum 57已经推出了对Gecko的重大改进(统称Stylo或Quantum CSS)，您可能会发现自己处于必须区分遗留版本的Firefox和Firefox Quantum的情况。
从我的回答来看:
You can use @supports with a calc(0s) expression in conjunction with @-moz-document to test for Stylo — Gecko does not support time values in calc() expressions but Stylo does: @-moz-document url-prefix() { @supports (animation: calc(0s)) { /* Stylo */ } } Here's a proof-of-concept: body::before { content: 'Not Fx'; } @-moz-document url-prefix() { body::before { content: 'Fx legacy'; } @supports (animation: calc(0s)) { body::before { content: 'Fx Quantum'; } } } Targeting legacy versions of Firefox is a little tricky — if you're only interested in versions that support @supports, which is Fx 22 and up, @supports not (animation: calc(0s)) is all you need: @-moz-document url-prefix() { @supports not (animation: calc(0s)) { /* Gecko */ } } ... but if you need to support even older versions, you'll need to make use of the cascade, as demonstrated in the proof-of-concept above.

下面的代码倾向于抛出Style lint警告:
@-moz-document url-prefix() {
h1 {
color: red;
}
}
而不是使用
@-moz-document url-prefix('') {
h1 {
color: red;
}
}

CSS支持可以从JavaScript中使用。
如果(CSS)。Supports ("(-moz-user-select:unset)")) { console.log(“火狐! !”) ｝

以下是针对Firefox浏览器的一些浏览器技巧，
使用选择器hacks。
_:-moz-tree-row(hover), .selector {}
JavaScript黑客
var isFF = !!window.sidebar;
var isFF = 'MozAppearance' in document.documentElement.style;
var isFF = !!navigator.userAgent.match(/firefox/i);
媒体查询黑客
这将工作，Firefox 3.6和以后
@media screen and (-moz-images-in-menus:0) {}

做到这一点的唯一方法是通过各种CSS hack，这将使您的页面更有可能在下一次浏览器更新时失败。如果有的话，它比使用js浏览器嗅探器更不安全。
