I have created a shortcut on their favourites bar to the Mozilla Xray Goggle page. I then want them to drag the bookmarklet to the bar. This works and I ask them to click on the first activity and then activate the Mozilla bookmarklet. This again works, the screen highlights in different areas but when I click on a section to remix, the html code editor will not appear at the bottom of the screen. It does on my machine so I'm thinking a setting somewhere but can't see anything obvious? Any help would be great!!
