Developer patches Codex to work with Arc browser via ChatGPT extension modification

According to GitHub repository arc-browser-use, Codex's browser control through the Chrome plugin in ChatGPT desktop app stalls on first tab open in Arc. A developer created a patched copy of OpenAI's ChatGPT extension that waits for Chrome's tab-group API before loading each tab, allowing Codex to list Arc as a usable browser.
