If browser.tabs.closeWindowWithLastTab is set to "false" closing "the last" tab does unfortunately not leave the browser with no tab (as in many programms with MDI) but with an empty tab named "New Tab" instead. 

This "New Tab" is replaced by the last closed tab if "un

Reproducible: Always

Steps to Reproduce:
1. set browser.tabs.closeWindowWithLastTab to false.
2. open two tabs, say http://nic.de/ and http://ripe.net/
3. close the second and then the first tab
4. invoke "Undo Close Tab"
5. invoke "Undo Close Tab"
6. invoke "Undo Close Tab"
Actual Results:  
4. -> "New Tab" is replaced by http://nic.de/
5. -> "New Tab" reappears right to the tab containing http://nic.de/
6. -> A new tab containing http://ripe.net/ appears between both tabs

Expected Results:  
The "consistent with 3.5 expectation:"

5. -> A new tab containing http://ripe.net/ appears right of the first tab.
6. do not offer "Undo Closed Tab".

The "natural" expectation:

3. -> really close last tab, leave non open (as classical MDI)
Implement "Undo Close Tab" as method of the tab container.
