Firefox opens a new window and moves the active tab to it. How do I stop this?

Got multiple tabs open. Firefox suddenly closes the tab I'm working on (this seems to happen when I'm scrolling) and moves it to a new window, shifting the focus to a previously inactive tab. What a swell feature! How can I get rid of it?

Chosen solution

Firefox 3.5/6 versions have a feature called tear-off tabs.

You can detach a tab from the current window and open it in a new window by dragging a tab in the browser window.

You can drag that tab back to the tab bar in the original window to undo that detaching.

Thank you very much, cor-el.

Please forgive my obtuseness, but do some people find tear-off tabs a useful feature? Why?
