Chrome Extension Support in Cursor Browser

Feature request for product/service

Cursor IDE

Describe the request

I am building a chrome extension - it would be fantastic if the native cursor browser supported the extension for testing and debugging purposes.

I second this. If the agent had the ability to view my extension running in the browser and programmatically access variables and trigger functions that my extension injects onto the page, it would significantly accelerate development. The fact that this concept of an agent live debugging a web technology at light speed might even be possible before 2030 would melt my 2020 self’s brain!

Also 1 upping this; was currently searching through documentation to see if this was possible. I wasnt sure if switching from Browser Tab to Google Chrome would mean it would load Chrome inside of Cursor, but it looks like it opens in an external Google Chrome window if I understand the documentation. I didnt test it out yet because this really isnt a priority for me right now, I am doing fine testing it in Chrome and going back and forth, but I think it would be pretty easy to enable this in the Cursor browser since it is built on Chromium. Would love to see this enabled and implemented.

Use the playwright.dev MCP which has access to your real browser and not an incognito session GitHub - remorses/playwriter: MCP to control your Chrome window via extension. Runs Playwright code in a stateful sandbox.. It can’t interact with the extension button in the toolbar, but it can interact with everything else e.g. panels, injected divs, reading scraped html etc

Thank you. I have been hearing a lot about the playwright MCP. I’ll test to see if this works with my extension. Thank you!
