When using the keyboard shortcut, CRTL+W, to close the current tab, if there's only one tab, the window itself closes.

Reproducible: Always

Steps to Reproduce:
1.Make sure "Always show the tab bar" is checked (Tool --> Options --> Tabs)
2.Have a single tab open or close all tabs except one.
3.Use the keyboard short to close the current tab CTRL+W
Actual Results:  
The window closes.

Expected Results:  
The current tab (single tab) should close and the window should remain open with a new tab and blank page.

This was working fine in the previous version 3.0.11

You can toggle the hidden preference "browser.tabs.closeWindowWithLastTab" in about:config to keep this from happening.

Ctrl+W shouldn't close the main window. Ctrl+W is the shortcut for closing the current tab (current MDI child in MDI environment) not for closing a main window (browser). For closing a window there is Alt+F4, and these two shouldn't be mixed.
If there are eccentrics who doesn't care if accidentally closes the window because pressing Ctrl+W they should be allowed to override the default behavior (they could because of browser.tabs.closeWindowWithLastTab pref).
