There was a time when using vimperator with firefox you'd always be able to focus the command prompt and enter a command like :q to close the tab, even if there's an active alert popup on the screen. It's hilarious to me that this thing is still a problem when it's technically trivial to solve. Actually I don't know if the feature was due to vimperator, firefox, or just my window manager.
