🚧 Sneak Peek: Chrome extension Manifest V3 for Security, Privacy, and Performance improvement

Support for the Manifest V2 browser extension will end this year on 31 December 2022. And new and existing browser extensions must use Manifest V3 technology to become available on the Chrome Web Store. Therefore, the Turn Off the Lights developers is already working very hard to get the Turn Off the Lights browser extension ready for you. As you can follow the Open-Source development on the public Turn Off the Lights Chrome extension Github page.

As the Google Chrome team said on this developer documentation page:

The Chrome extensions platform continues to evolve. The specific course we’re steering focuses on improvements to security, performance, and privacy — while preserving or extending the capability of extensions and keeping a webby developer experience.


However, the development of the Turn Off the Lights browser extension from Manifest V2 to Manifest V3 involves some massive code changes. And takes time to get right for the desktop and mobile users. Even the Camera Motion and Speech Recognition features will not be available anymore because of the limation of the Manifest V3. Because it cannot access the <video> and <audio> elements on the background script page, to get the speech analysis and hand gesture detection.

Although Google Chrome said that Manifest V3 is stable for developers, it still contains some huge bugs that need to be fixed in order to get a good experience for the users.
