Hey, thanks for the report. I see three related issues: browser debugging is misleading, the terminal hangs, and the agent breaks already fixed code.

This is a known set of issues. Please check in order:

1. Terminal hangs - most common root cause of the others:  
Settings \> Agents \> “Legacy Terminal Tool” - try toggling it, then `Cmd+Shift+P` \> “Terminal: Kill All Terminals”, restart Cursor.  
If you use Oh My Zsh/Powerlevel10k/Starship - they can break the agent’s command completion detection. Details: [🛠️ Guide: Fix Cursor Agent Terminal Hangs Caused by .zshrc](https://forum.cursor.com/t/guide-fix-cursor-agent-terminal-hangs-caused-by-zshrc/107260)

2. Browser debugging for backend:  
The built-in agent browser is fine for UI tests, but not great for complex backend tasks. For full debugging, use MCP Browser Tools:

3. Agent breaks fixed code:

4. Extensions can cause hangs:  
Run `cursor --disable-extensions` and see if it still reproduces.

To diagnose precisely, please share:

- Request IDs of problematic requests (Privacy Mode off): [Getting a Request ID | Cursor Docs](https://cursor.com/docs/troubleshooting/request-reporting)
- Which shell you use (zsh/bash/fish) and any prompt themes (oh-my-zsh, powerlevel10k, starship)
- A screenshot of the agent’s stuck terminal
- The specific command that hangs
- Your installed Cursor extensions
- Settings \> Network \> Run Diagnostics - the result

Share the details and I can help more precisely or escalate to the team.
