I have added a menu item to the contentAreaContextMenu
(right-click) menu and I need the menu item when clicked to open an HTML page as a popup, much like the way you see this "Google news" one. I have read that an <iframe>
is used for this but after so much reading I still don't kow how to get the popup to open and show the HTML page (popup.html
).
If anyone has a suggestion or knows how to do this please help. Its my first Firefox extension.
