OpenAI’s Codex, the coding agent baked into ChatGPT, now officially supports Microsoft Edge through its Computer Use feature. Edge is the first browser outside of Chrome to get the treatment, and it arrives with a new “More browsers” section in the Codex settings.

What actually changed

The Computer Use feature lets Codex perform tasks across local applications and web sessions after users grant permissions. Think of it as giving the AI agent the ability to read webpages, navigate between tabs, and execute actions, all within the browser environment.

Previously, that capability was Chrome-only. Now Edge gets the same treatment, meaning Codex can access context across tabs and automate browser-based actions in Microsoft’s default browser.

The update is accessible through a new “More browsers” section in the Codex settings. For now, Edge is the only browser listed there, but the naming convention suggests more options are coming.

This isn’t the first time users tried to make Edge work with Codex. GitHub issues from mid-2026 show developers attempting workarounds for Edge compatibility well before official support landed.

The timeline and context

Codex launched as a standalone tool in February 2026, initially supporting macOS only. The Computer Use plugin followed in April 2026 on macOS, with Windows support arriving on May 29, 2026, via version 26.527 of the Codex app.

The coding agent is available across ChatGPT Plus, Pro, Business, Enterprise, and Edu plans.

Why this matters for developers and enterprise users

Developers in Microsoft-heavy shops have had to either switch to Chrome for Codex workflows or simply skip the browser automation features entirely. Switching browsers breaks the flow of enterprise-managed environments where IT teams control browser policies, extensions, and security settings.

The practical upside is straightforward: developers can now use Codex’s Computer Use feature to automate web-based tasks, pull context from documentation open in Edge tabs, and interact with web applications, all without leaving the browser their company already manages.

No pricing changes or new plan tiers were announced alongside the Edge update.
