How to open new tab in popup window

I would like to h开发者_运维问答ave a button/link in a page with the following behavior:

• On the first click, open a pop-up.
• On later clicks, if the pop-up is still open, open a new tab in pop-up window.

I tried to achieve this with in Firefox, but whatever I do non-first pop-up opens in parent window.

Any ideas?

I do not think this can work with browser tab. But you can use javascript to display the contents in a DOM tab i.e. the popup window can display tabs.

I hope it helps.
