DHTML Window widget FF1+ IE6+ Opr8+
This is a robust DHTML Window widget that replicates the look and functionality of a  traditional pop-up window, minus the intrusiveness. Drag or resize the window widget on the page, minimize or close it, load a new page into it, or spawn whole new windows just as you would with popups. It's a modern, web 2.0 alternative to pop-up windows! Add-on #1- DHTML Modal window:
This addon script extends DHTML Window widget with modal windows support. A modal window differs from a regular DHTML window in that a "veil" appears over the rest of the page whenever the modal window is open, requiring the user to explicitly close it before the veil is lifted and the user can interact with the page again.
