Greetings, I sometimes get this error: Warning: unresponsive script A script on this page may be busy, or it may have stopped responding. You can stop the script now, open the script in the debugger, or let the script continue. Script: chrome://browser/content/browser.js:16594 How can I find out what tab this is for? The dialog box sometimes appears in the top left of the desktop, outside of the Firefox window. Thanks, Shane.
