Ever since I upgraded to the new version of Firefox, I've been getting these messages now and then whilst browsing the web:
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.
Script: chrome://browser/content/tabbrowser.xml:0
What's that? Why do I get it? How do I get rid of it? Cheers
