Facebook Canvas and WebGL problem

I have a problem with facebook canvas and web gl... If i go directly to the address of the game hosted in my google drive herE: https://b1754d066320e56286ea139f5db4fa41b2d2c00d.googledrive.com/host/0B6aEHRQAY6txfmVSMkM1M2NST0QtT3Y2cjZEZVA3Q2dEeFFPS05qUG9MeUw1ZUFxLUR4LVU/ everything plays fine (the game is around 300mb), if i post the link from my game to facebook canvas and hit publish and then go to the facebook address of my game , i just see a white screen... Is there a size limit for facebook canvas?? and if so is there a way to decrease the size of the game in webgl?? if i just exprot for web its just 40mb (and it makes sense because the game is not that big) any help would be much appreciated
