236834 - suggestion: window close button should be disabled when there are multiple tabs open

Status: RESOLVED DUPLICATE of bug 68215

(Firefox :: Menus, enhancement)

Description

[Chris Peterson [:cpeterson]]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Gecko/20040206 Firefox/0.8

The tab close button is very close to the window close button. Thanks to Fitt's
Law, I often accidentally hit the window button when reaching for the tab close
button. Firebird exits and I lose all my tabs! I think the window close button
should be disabled when the tab close button exits. The user can still exit the
browser using the File>Exit or System>Close menus.

Reproducible: Always
Steps to Reproduce:
1. Open multiple tabs
2. Try to close a tab quickly
3. Notice that, thanks to Fitt's Law, you can easily hit the window close button
instead of the tab close button! :-(

Actual Results:  
The window closes and I lose all my tabs.

Expected Results:  
The window should not close and I do not lose all my tabs.

Nightly builds already have a feature to warn you if you try to close a window
that has multiple tabs open.
