When I'm online, while the page is still loading I get 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. Script: chrome://fctoolbar51ef49d2624b41948b971c468e9b0efe/content/fctoolbar.js:1 I get this message multiple times while a page is loading. This has slowed down my computer to unbearable and often the computer freezes and I have to restart.
