Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

When using the integrated browser in v2.4.x, the browsers developer tools cannot be undocked like they use to be in v2.3.35. This is reducing the screen real estate available for the page I’m trying to debug. Moving to a new window then trying to show the dev tools crashes cursor.

Steps to Reproduce

Use the integrated browser, then click show console. You will see the dev tools docked with the browser.

Next, Move to a new window, then click show console. Cursor crashes and closes.

Expected Behavior

Dev tools should open in it’s own window like it use to in v.2.3.35!

Operating System

Windows 10/11

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. Both cases you described are known bugs:

  1. DevTools can’t be undocked. This is a regression in v2.4.x. DevTools are currently forced to stay docked inside the browser panel.
  2. The crash when opening the console in a new window is a broader bug related to moving the browser tab into a separate window.

There’s an existing thread tracking the same issue with more details: Browser tab becomes unresponsive after moving to a new window (v2.4.22)

The team is aware. No ETA yet, but reports like this help with prioritization.

Workarounds:

  • Keep the browser tab in the main Cursor window (don’t use “Move to new window”)
  • Or open your page in a regular browser for debugging with full DevTools

Let me know if you have any questions.

Hi Dean, the regression on DevTools is a bad decision in my view as it is more useful to move the tools window out of the way to focus on app building and debugging. Having it docked forces a user to work in a much smaller space than they may desire. Is there a vote to ask your community if they want to keep DevTools docked or revert to a free floating panel?
