No, C-shift-w closes the window. C-q Quits the application, meaning it would close all of your Windows. And if the entire application closes, a hotkey to bring the window back won't work. That's why it's so frustrating when I click it by accident.
Well, if I were, say, typing up a forum post, that would be lost. More often, however, I simply lose all my tabs. Which are not impossible to restore, given Firefox's "Restore Previous Session" button. But since I have the Cookie AutoDelete extension[0], all my sites get logged out. So I have to re-authenticate with my password manager, log back into all the sites, half of which require me to pull out my 2FA token...
It only takes about a minute total to get back up and running on everything. It's just a nuisance when it happens.
Thanks for the downvote, whomever. I always consider switching to Firefox, as I think Chrome needs competition, but Firefox has just never been up to par in usability (especially developer usability) whenever I've tried to switch. Things like "losing your work" for no good reason (don't Firefox have "Re-open closed Window"?) is just another thing I would add to the list of reasons not to switch, so feel free to clarify.
> (regardless of whether you have automatic session restore enabled for restart).
It also already has an optional check if you want to close a window ("you're closing a window with 10 tabs. sure?"), and a list of recently closed windows to restore.
I interpreted the change as if it would always show the quit warning regardless of any settings, since the warning popup is not exactly a new feature. Some more context helped clarify.
Can't tell you how many times my finger has slipped and hit Ctrl+Q instead of Ctrl+W.
Oh well! I didn't need all that work...
