Browser refuses HTML debug run

### Apache NetBeans version

Apache NetBeans 14

### What happened

I have an HTML/JS app I'd like to debug. I am on NB 14 and Linux. The Chrome extension is installed.

When I attempt to run "index.html". the browser comes up correctly. However, I get a message:

Browser refused to debug this tab.
Close Chrome Developer Tools (or any other browser debugger) and try again.

I completely rebooted my machine, logged in, and ran NetBeans. I didn't start anything else. I'm still getting that error.

### How to reproduce

_No response_

### Did this work correctly in an earlier version?

No / Don't know

### Operating System

Fedora Linux

### JDK

8

### Apache NetBeans packaging

Apache NetBeans provided installer

### Anything else

_No response_

### Are you willing to submit a pull request?

No

### Code of Conduct

Yes

The report only identifies index.html, NetBeans 14, Fedora Linux, JDK 8, and the Chrome extension; start by reproducing the failed debug launch with that setup. Done means the HTML/JS tab can be debugged without the “Browser refused to debug this tab” message, with the responsible entry point or diagnostic identified.
