Why these messages?
 

I am receiving the following messages

Fire fox has not closed

or

script is busy continue, debug end" ?????

I am not sure about the 'not closed' message, but you can go to task manager (CRTL-ALT-DEL, select task manager, and on the processes tab see if foxfire is running. If so, then for some reason it did not close when you closed the window. I would suggest remove the program and re-install.

As for the long script, I have seen this many times, I am guessing the site you went to has a problem, generally selecting STOP will work.

Hope this helps.
