Bug: Browser tab unresponsive after moving to new window (v2.4.22)

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

After updating Cursor IDE to version 2.4.22 (VS Code 1.105.1) on Windows 10/11, the browser tab becomes unresponsive when moved into a new window. When I open http://localhost:3000/ or any webpage inside the IDE and use the “Move into new window” option, I cannot scroll or click on the page. The select element, show console and show CSS inspector tools also stop working. This happens on both my notebook and PC, so it doesn’t seem to be related to my project.

Steps to Reproduce

  1. Update Cursor IDE to version 2.4.22 (VS Code 1.105.1).
  2. Open a Browser Tab inside the IDE with any URL (e.g., http://localhost:3000/ or any website).
  3. Right-click the tab and choose “Move into new window”.
  4. In the new window, try to scroll or click inside the page.

Result: the page becomes unresponsive (no scrolling, clicking or tool interactions).

Expected Behavior

The browser tab should remain interactive after being moved to a new window. I should be able to scroll, click links, and use the inspection tools (Select Element, Show Console, Show CSS Inspector) as usual.

Hey, thanks for the report.

This is a known issue and the team is aware of it. The bug is related to moving the browser into a new window.

Workaround until there’s a fix:

  • Keep the Browser tab in the main Cursor window (don’t use “Move into new window”)
  • Alternatively, open localhost:3000 in a regular browser

Could you clarify a couple of things:

  • If you keep the Browser tab in the main window, does everything work normally?
  • Does it happen on any URL, or only on certain sites?

Let me know if the workaround doesn’t help or if you have more details.

Thanks for the quick response and for confirming the team is aware of this. I can confirm that keeping the Browser tab in the main Cursor window works normally—scrolling, clicking and inspector tools all function as expected. The unresponsive behavior only occurs after using “Move into new window” and affects any URL I’ve tried, including http://localhost:3000/ and external sites. Opening the pages in a regular browser is a workable workaround, but being able to split the Browser window inside Cursor would be very helpful for my workflow.

I’ll stick to the main window for now and avoid moving the tab. Please let me know when a fix becomes available. Thanks again!

This bug prevents the effective usage of Cursor on multi-monitor setup. Please pay more attention to it. Thanks beforehand!

Is there any estimate for when this bug will be fixed?

Unfortunately, there’s no exact ETA. The team is aware of this bug, but I can’t say when the fix will ship.

What you and @Zoin pointed out about the multi-monitor workflow is especially important.

For now, the workaround is to keep the browser tab in the main window, or use a regular browser. We’ll update this thread when there’s anything new.

Cursor IDE

Describe the Bug

Browser contents become unresponsive when the browser tab is moved to a new window. Attempting to open the console in that window crashes the entire IDE.

Steps to Reproduce

I open my project.
I spin up a web application via the cursor terminal.
I open a browser tab.
I right click and move the browser tab into a new window.
The browser contents (the webpage) becomes unclickable / unresponsive.
When I hit open console in the top right corner, the entire app crashes.

This ONLY happens when it is in a separate window, now when its an embedded tab.

Expected Behavior

It should not crash.

Describe the Bug

Moving the built-in Simple Browser to a new window causes Cursor to crash and close completely. Reproducible every time.

Launch a web application by opening the built-in simple web browser, instead of using Chrome.
Once the browser window is opened as a tab in Cursor, select the tab, right-click and select “Move into New Window”.
The entire Cursor application will crash and close completely.

Expected Behavior

Simple browser is moved into a new window that is not within the Cursor IDE environment.
