Status: UNCONFIRMED

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/534.7 (KHTML, like Gecko) Chrome/7.0.517.44 Safari/534.7
Build Identifier: Firefox 4 beta 8

In FF, if we open multiple tabs, then there would be a different document as per tab. In FF3.6 we used to identify the document of the relevant tab using document window handle. With FF4.0 the HWND structure has been changed and there is now only one top class i.e "MozillaWindwoClass". So for every document it will return the same HWND.

Is there any way in FF4.0 to identify which document belongs to which tab.


Reproducible: Always

Can you explain what you need in more detail? Are you trying to get the screen coordinates of a document?

You can get the screen coordinates with an extension using window.mozInnerScreenX/Y and window.innerWidth/innerHeight, multiplied by DOMWindowUtils.screenPixelsPerCSSPixel.

I don't understand how you're identifying tabs, but extensions can easily figure out the relationship between tabs and documents. (I don't know the details.)
