MetaMask 浏览器插件无法启动解决法方案

在没有备份过助记词/私钥，同时重启插件/电脑均无法解决的情况下，可在电脑本地全局搜索 nkbihfbeogaeaoehlefnkodbefgpgknn，这是 MM 扩展 id，如这个目录下：C:\Users[User]\AppData\Local\Google\Chrome\User Data\Default\Local Extension Settings\nkbihfbeogaeaoehlefnkodbefgpgknn 找到 ldb/log 这些文件，在这些文件里找到如图目标内容。 后用 https://metamask.github.io/vault-decryptor/解开这段目标内容，Password 就是目标 MetaMask 扩展的密码。

若 MM 的任意扩展页面可以打开，比如：chrome-extension://nkbihfbeogaeaoehlefnkodbefgpgknn/home.html，则用下面的方式也有得到待解密的内容：

chrome.storage.local.get('data', result => {  
    var vault = result.data.KeyringController.vault  
    console.log(vault) })
