Suddenly started running ultra slow before telling me a script was busy. Worked for years but now nearly unusable.
as it says in the question

see the following article
for suggestions and let us know if it helped.
I had this problem after a recent Windows update. Any site that used Flash was impossible to use and after a very long delay, gave me the busy script dialog. The fix was:
Disable the Flash Player plugin's protected mode. See this support article from Adobe under the heading "Last Resort": Adobe Forums: How do I troubleshoot Flash Player's protected mode for Firefox?
Hopefully that will help.
