今天是Firefox 61正式发布的日子，随之而来的是Beta测试通道的更新，Mozilla Firefox 62 Beta 3加入了全新的策略引擎，现在可用于在企业环境中自定义Firefox部署，增加了对Web身份验证的支持，允许使用USB令牌对网站进行身份验证，并让新的CSS引擎开始运用于用户界面，改进可谓不小。
- The policy engine is now available to customize Firefox deployments in Enterprise environments (more details on https://wiki.mozilla.org/enterprise)
- Added support for Web Authentication, allowing the use of USB tokens for authentication to web sites
- Locale added: Occitan (oc)
- The new CSS engine introduced in Firefox Quantum (57.0) is now used for the browser's user interface, in addition to web content.
- On Windows, the shortcut for entering Reader View has changed to F9, for better compatibility with keyboard layouts which use AltGr.
- It is no longer possible to have multiple bookmark keywords for the same url, unless the request has different POST data.
- Enhanced camera privacy indicators: Firefox now turns off your camera when you face-mute on web-sites that use your camera, turning off your camera light so you don't have to wonder if the site is still recording you. The light will come back on whenever recording resumes.
- Responsive Design Mode now offers explicit control over whether the page should reload.
- Developers can now use promises within IndexedDB transactions
