Rightclick Menu

Hi,

In my site, i have a inbox as like yahoo & gmail inbox. I am trying to build a rightclick option for my messages which includes reply,open in new tab,open, etc.,. Is that possible to build right click menu using JAVASCRIPT without jQUERY. I heard that contextmenu wont work in Firefox. Can some one please help me?

Thanks,
Priya
