Chrome Extension Support in Built-in Browser

Feature request for product/service

Cursor IDE

Describe the request

It would be extremely valuable if Cursor’s built-in browser supported loading Chrome (Chromium) extensions in developer mode.

This would enable developers to build and test browser extensions directly inside Cursor, while leveraging its integrated debugging, UI inspection, AI editing, and code navigation features - without needing to constantly switch to an external Chrome window.

Suggested capabilities:

  1. Load unpacked extensions (developer mode)

  2. Support for background scripts, content scripts, and service workers

  3. Extension popup testing

  4. DevTools access for extension contexts

  5. Automatic reload on file changes

This would make Cursor a fully self-contained environment for extension development and significantly streamline the development workflow.
