Come on??? Why are the comments about Firefox 100% ignored? If it can't work in Firefox please say so rather than ignoring the members.
I understand that the world has not yet seen past IE, but some forums do have a pretty big userbase of Mozilla users.

Is this issue not able to be addressed? I have tried it in Firefox, I do get the dialog for right click is disabled, as soon as I click ok the right click menu pops up. But hey this does work great in IE. Excellent mod and great idea on the images only concept!
