On May 8, 2026, OpenAI made waves by unveiling the Codex for Chrome extension, which seamlessly integrates Codex support into the desktop versions of the Chrome browser for both macOS and Windows. Once installed, this extension empowers Codex to leverage the browser's environment to test web applications, gather contextual information from multiple tabs, and access developer tools—all without interrupting the user's browsing experience. This allows Codex to perform tasks in scenarios that closely mimic real-world conditions. To get started, users simply need to update their Codex software and then install the Chrome plugin. After installation, they can interact with the browser via the "@Chrome" command in Codex. The extension operates in a dedicated tab, supports multitasking, and grants users control over the websites that Codex can access. Currently, this extension is available worldwide, with the exception of the EU and the UK.
