Ditto. I've been 'trained', so to speak, all this time that Safari would warn me if I mistakenly hit Cmd-Q instead of Cmd-W (or didn't realize I was back in Safari and hit Cmd-Q). I don't do it a lot, but when I do it's incredibly frustrating.
And yes, I _know_ there's a 'Reopen windows from last session' option, but that doesn't mean anything if I'm logged out of something when the browser closes. That just means I'll have 12 'please log in' windows.
Please add this option back. It's ridiculous to take it out just because there's a soft feature that sort if kind of mimics the behavior after-the-fact.
Is there ANY way to force Safari to warn me before quitting with multiple tabs open?
Terminal? Extension? Collaring and shouting at Safari programmers? (and reporting a "bug" to Safari people has never in 10 yrs resulted in any fix for me)
