Don't ask again, No accelerator
Bug description
With the preference confirm_close_multiple_tabs activated the following dialog appears when closing a window with several tabs:
You are going to close several tabs Do you really want to close them all?
[Checkbox for "Do not ask me again"]
[No] [Yes]
The checkbox for "Do not ask me again" and the option "No" both use the letter n as shortcut, so pressing alt+n alternates between the options instead of selecting one.
Steps to reproduce
In the Advanced Configuration Editor set the value of preference confirm_close_multiple_tabs to Activated. Close a message window with several tabs.
