Close Recent Popups par em_te

Use the toolbar button to close the last opened popup window based on a set of criteria:

1. Only popups older than 0.5 seconds will be closed
2. Popups older than 3 minutes will not be closed (you will be notified)
3. If a popup is closed by its own website, the button is disabled for 0.5 seconds
4. Popups with 2 or more tabs open will not be closed
5. Successive clicks on the toolbar button will close popups in reverse chronological order

On first install, there is a demo page which allows you to open a popup and then test clicking on the toolbar button.
