Started happening for me on TR yesterday.
“A script on this page may be busy, or may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.”
It doesn’t. I select, “Stop script”, as opposed to, “Continue”, in the warning box.
Each time, the script is identified as,
Script:chrome://noscript/content/RequestWatchdog.js:1102″
I am assuming the box comes of NoScript. I am running XP Pro, SP3 up-to-date, with Firefox.
Is my experience unique?
