How optimistic.

No I believe that he meant exactly that and even then he wouldn't "have been convinced". The engineers never are (about usability issues)

So Crtl+F being mapped to the find command in every other application wasn't "a really good reason"?

No, it's a good reason. It's just that this particular user wasn't aware of that good reason, and because of sacred cow syndrome no one would tell him otherwise.

Or better yet, Bill Gates wanted user configurable keyboard shortcuts.

Users can't handle that. Better leave the Ctrl-Q [Quit without asking] shortcut immediately next to the Ctrl-W [Close tab]. Love, the Firefox devs.

Hmm. I'm on Firefox/latest on Windows, and Ctrl-Q does nothing.

Is this a Linux thing?

I do accidentally close Firefox from time to time, though: The problem is that Shift-Control-W is "close window" instead of "close tab". Which makes sense, but sometimes I hit it by mistake, typically when I mean to hit Shift-Control-T. Don't know there's anything they could do to fix that.

I know I do hit Command-Q instead of Command-W almost every day on my Mac. I've installed a big keyboard macro application so that I can remap "Command-Q" to "nothing", I literally don't use it for anything else.

Sometimes this piss me off too.

But this is worse. Pressing Command+W in Skype chat asks if you want to remove person from your favourites. At one specific version it actually closed the window. Go figure.

Allow shortcut keys to be remapped.

Would be nice, but both shortcuts "make sense" to me, which makes them easier for me to remember.

Though considering "close window" is so disruptive when you hit it by accident, an optional "close the window?" dialog would be nice.
