我的Wordpress网站上有一个滑块，不再在Firefox 49或50上加载。加载指示器出现但不会动画或显示和滑动。适用于Chrome和IE。下面是JQuery。有没有理由在新版本的Firefox中出现这种情况？

答案 0 :(得分：1)
看起来API正在调用一个带有一个参数的函数。
Mozilla弃用了这个：https://developer.mozilla.org/en-US/docs/Web/API/CSSStyleSheet/insertRule
并导致错误：auto where = mymap.find(key);
if (where == mymap.end())
where = mymap.emplace(key, expensive_function(key)).first;
您可以尝试将索引添加到insertRule（在本例中为0）
TypeError: Not enough arguments to CSSStyleSheet.insertRule
