[SOLVED] Yahoo finance functionality gone

I had this problem about a year or two ago and I can't remember what I did to fix it. Basically you should be able to move the mouse pointer over the price chart then a small dot moves across the chart and the price at that time is displayed in the corner. Now none of that works. I tried reinstalling Flash and Java. Still not working. I'm going to try reinstalling Firefox. Otherwise I'm thinking that a Windows update screwed this up.
