Netbeans 10 doesn't run html pages in the browsers - netbeans

Question

I have Apache netbeans 10 on Ubuntu 18.04 64 bit.
I created a simple html5/javascript project but when I run it in the notification area I have the error:
Cannot run /usr/bin/google-chrome
I have already manually installed chrome netbeans extension but nothing. I have the same problem with Firefox and the default web browser. Which could be the problem?
Finally, when I run the binary file netbeans from shell to open Netbeans I have following warning:
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.netbeans.core.windows.view.ui.MainWindow (jar:file:/home/nick/netbeans/platform/modules/org-netbeans-core-windows.jar!/) to field sun.awt.X11.XToolkit.awtAppClassName

Recently I was having the same problem, when trying to run a HTML5 NetBeans-Project using Chrome, on NetBeans 12.0, CentOS7. Here is what I did to be able to run the Site on Chrome through, NetBeans Run's Command-Bar Option.
Select Tools>Options.
On WebBrowser List, select Chrome
Press Edit Button
The WebBrowsers Manager window will open.
In the Process opt., search for Chrome-App. E.g. /usr/bin/google-chrome-stable
In the Argument's Textbox, set: --no-sandbox {URL}
Press OK for each Window until all are closed.
On the Run's Button Bar select Chrome.
Press Run; then Chrome should launch your HTML5 Site.
Note: A warning will be prompted on Chrome due to -no-sandbox param.
