When user clicks on Assign Roles button in the project, it pops-up Add/Remove Roles window and it throws up the following error message, A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete. Issue is noticed in Firefox.



This happens when you have huge list of roles to be populated in the Assign roles window but the time out value for the java script in the browser must be set to low value.


  • Launch Firefox.
  • Type About:Config in the address bar.
  • When you see the warning message, click on I’ll be Careful, I Promise button.
