Question

We are a bit in trouble.

We show some informations for specific sites in our own firefox extension (for several reasons we use a xul box-Element for that presentation).
We don’t wan’t the box to show in browser popups.

But: How do we identify a browser-window as a popup in our extension code (javascript)?

Thanks a lot!

Answer 1

You may check:

1. if the window does have an opener => if(window.opener)
   to determine if it was opend using javascript
2. if the window does have an opener, check if it is the top-window =>if(self==top)
   to determine that the window is not a frame

When both conditions are true, you may assume that the window is a popup.
