Chrome Experiments: Pop-up window without No-Script button

[MrX1980]

Hello

I have just noticed that there is no No-Script Button in the Aurora (Firefox) Pop-up Window of the "Chrome Experiments" webpage.

a) http://www.chromeexperiments.com/webgl
b) select one of the examples/experiments
c) click on "Launch Experiment"
d) a pop-up window opens without the No-Script button

I have tested it with placing the button in the add-on bar or right to the back/forward buttons.

My WOT (web of trust) button is available so it should be possible.
