我的 Firefox 版本是 188，所以我知道这不是版本问题。每当我“检查”然后控制台时，我都会收到以下错误。
未捕获的语法错误：导入声明只能出现在模块的顶层'
我在这个项目中总共只使用了三个文件和一个文件夹：“index.html”、“logic.js”和一个“data”文件夹，其中包含我的“trueData.json”文件。
索引html文件代码：

trueData.json 有 25057 行代码，所以我只关心显示其中的前两个对象；如果有人想复制我的错误，请删除第二个对象的对象逗号末尾，以便于复制和粘贴。

我为尝试解决此问题所做的工作：
ES2015 导入在 Firefox 中不起作用（即使在顶层）
将“模块”添加到行> 在我第四次尝试解决该问题时，在 html 文件中。错误消息保持不变。
尝试使用 Bing AI，当我已经完成步骤 2 时，它建议执行步骤 2，并查找我的 Firefox 版本号。 Firefox 是最新的，因此logic.js 代码应该可以工作。错误仍然相同。
我不知道控制台除了该错误消息之外什么都不输出。
added 'module' to line <script type = "module" src = "./data/trueData.json"></script><script type = "module" src = "./logic.js"></script>
