无法在 Mozilla Firefox 中自动下载 jre，但在 IE 中工作正常
我无法在 Mozilla Firefox 中自动下载 JRE，但它在 IE 中运行良好。 目标是让用户无需自己寻找就能拥有JRE。

I am unable to download JRE automatically in Mozilla Firefox, but it works well with IE.
The target is for the user to be able to have a JRE without searching for it by himself.

我认为问题可能出在您安装的 Firefox 中。
Firefox 不加载 jre 有多种原因（例如，如果他已经有 jre 或者有什么东西正在积极阻碍他）。
尝试在一台干净的机器上安装一个干净的 Firefox，最好是刚刚安装的机器，然后再次测试。
那么可能是 Firefox 不知道 cab 文件是什么（尽管这不太可能）并且拒绝调用它。要测试在 Firefox 中打开 cab 文件，如果出现保存文件对话框并且无法打开文件（而不是保存文件），则可能是问题所在。
您正在使用什么 Windows？您是否在其他 Windows 上进行了测试？
祝你好运。
I would assume that the problem could be within your installation of firefox.
There are multiple reasons why firefox will not load the jre (e.G. if he already has one or something is hindering him actively).
Try to get a clean Firefox installation on a clean machine, preferably one you just installed and there, test it again.
Then it could be that Firefox doesn't know what a cab file is (though this is unlikely) and is refusing to call it. To test that open the cab file in your Firefox, if the save file dialog appears and does not provide you with a possibility to open the file (instead of saving it) that could be the problem.
What Windows are you using and have you tested it on other ones?
Good luck with this one.
