I'm running Firefox 6.0.2 and that chart runs successfully in the Flash player. Any reason you're still running Firefox 4.0.1? That definitely is not the latest version...

Hi,

I have installed Firefox 6.0.2 Version and I still have problem in viewing the Google charts. Please have a look at the below pie chart link: http://code.google.com/apis/chart/interactive/docs/gallery/piechart.html

Thanks for the link. That one doesn't use the Flash player, so the problem must be somewhere else.

If you use NoScript or other security add-ons, make sure google.com or code.google.com is allowed to run scripts.

Could you try disabling graphics acceleration and see whether that makes any difference?

orange Firefox button or Tools menu > Options > Advanced

On the General mini-tab, uncheck the box for "Use hardware acceleration when available"

This will take effect after you restart Firefox.
