Today I got something interesting experiences with my firefox browser, when I working for my final year project ( eID - www.project-eid.org ). I needed to develop a firefox extension for the client side application of the eID system. So I tried some codes and try to finished it in a hurry. Because I needed to finished today. My supervisor asked me to show a demo on my work. I coded the following codes in the browser.xul file to overwrite the firefox browser.xul file.

<window id = "main-window"> <iframe id = "eID_popup" src = "about:blank" /> </window >

And then I created the .xpi file and install it to my firefox. Actually I needed to load a customized chrome URL inside the browser window. But actually what happened was...

see this nice pictures...



My browser window has spilled into two windows. One main window was in the actual position, and other one was beyond the status bar. Then I tried another code ...

< window id="main-window">
    < iframe id = "eID_popup" src = " about :blank " position = "1" / >
< / window >

It shown the following effects in my firefox browser.



Now also my browser window has spilled into two windows. One main window was in the actual position, and other one was in the top.

Therefor I asked one of my friend, what could I do for that problem. He gave me some crazy idea to release that extension as a new extension to spilt the firefox's window. What a funny :) ....
