The noscript in ff4 beta 11 is filter out the embedded image in google spreadsheet.

I try to embedded the image link in google spreasheet

It only can be seen while noscript is disabled.

gstatic.com and googleusercontent.com has be added to allowed and I have also tried ff4pre12 and noscript 2.0.9.8rc3 but no change.
