Close Button is an extension which adds a Close Tab (or Window, or Browser) button to the toolbar.
This is especially handy if you put your tab bar at the bottom but want a Close Tab button in the top right, where you'd find it in most well behaved Windows programs with child windows.
Once installed, just right click on the toolbar, select "Customize...", and drag the button wherever you like. The button's appearance is determined by the installed theme, and its behavior can be configured to close the current tab, window, or Firefox session.

What's New in This Release: [ read full changelog ]
· Compatibility updated to 4.0
· Fixed issue where the button would sometimes disappear, but reappear when the extension was reinstalled -- for example, this would happen when switching FF versions.
· The button WILL disappear from your toolbar as a result of this update; find it in the "customize" dialog and put it back where you want it. This is a consequence of fixing the previously mentioned issue, which is why I've been putting off fixing it. Sorry for the inconvenience.
