# 主流浏览器中如何清除HSTS设置

HSTS（HTTP Strict Transport Security）国际互联网工程组织IETE正在推行一种新的Web安全协议

HSTS的作用是强制客户端（如浏览器）使用HTTPS与服务器创建连接。

## Chrome、Opera：

1. 在地址栏输入“chrome://net-internals/#hsts”
2. 在“Delete domain”的输入框中输入域名
3. 点击“Delete”按钮
4. 在“Query domain”的输入框中输入刚才的域名
5. 点击“Query”按钮
6. 如果看到“**Not found**”则表示清除成功

## Safari:

1. 关闭safari浏览器
2. 删除“\~/Library/Cookies/HSTS.plist”文件
3. 重新打开safari浏览器

## Firefox:

1. 关闭站点的所有标签页
2. 清除历史数据
3. 在地址栏输入“about:permissions”
4. 搜索并且点击站点
5. 点击“Forget About This Site”

\*从Firefox 45已经移除“about:permissions”页面，故此方法只在45版本以下适用。
