OpenAI Developers posted on X that Codex can now take on more browser development work through a new Chrome plugin in the Codex app. The post states that the tool can "test web apps," "gather context across tabs," use web DevTools "efficiently in parallel," and keep results organized "without taking over your browser."
The announcement drew a mixed response. Some commenters welcomed the browser-focused workflow, with one user calling the plugin "great and very useful," while another described browser context as "the missing bridge" between writing code and understanding how a product breaks from a user’s point of view. Others focused on practical questions, including whether the feature requires a ChatGPT sign-in or works with an API key, and whether it is available through a specific Chrome profile.
A few replies pointed to possible friction. One user claimed the extension was "disconnected" regardless of what they tried, while another reported that the feature "failed big time" when asked to move Twitter search results into a Google Sheet. Several commenters also pressed for details on auth state across tabs, SSO in enterprise settings, and whether parallel browser sessions can stay isolated from one another.
