"TypeError: define is not a function" in firefox

[frague59]

Hi,

I've a n error while using widgy with firefox :
"TypeError: define is not a function"
"TypeError: geometry is undefined"
...when I go to "/admin/widgy_mezzanine/widgypage/1/" page.

But in chrom[e|ium], it does work perfectly. It works "sometimes" with fiefox... My setup is pretty standart, I follow "official" tutorials.

Thanks for your help !
