Firefox 100 on Windows 7 requires KB4474419 Update to install

shang2010

Starting Firefox 100, Windows 7 SP1 users must have installed the KB4474419 update to install Firefox, otherwise, its installation may fail. This is because Mozilla has signed Firefox for Windows installer with a SHA-256 digest than SHA-1.
从 Firefox 100 开始，Windows 7 SP1 用户必须要安装 KB4474419 更新之后才可安装该浏览器，否则会提示安装失败。这是因为 Mozilla 对 Firefox for Windows 安装程序的签名是 SHA2-256 摘要，而不是 SHA-1。
