That is very obviously the point. Users have been asking for this feature for years. All other browsers do it, there is no reason for opera not to have it. And there is NO reason not to add it in newer versions. None.

Opera moderator Leocg:
Once again you have brushed off a simple query that has not been answered and locked my thread.
All I want to know, and all the rest of these users who have asked for this feature want to know is why does Opera for Windows have no confirm close dialogue but Mac does? If a reason can be given, that would be great and the matter would be closed. Unfortunately, you have left me no choice but to report your unhelpful and inappropriate behavior (including your sarcastic and disrespectful comment in another thread https://forums.opera.com/topic/8567/warning-exit-dialog-when-having-multiple-tabs/23) to customer service via email (social-networks@opera.com). Most unfortunate indeed.

Like I say later, if this cannot be done, just explain why and the matter will be closed. You are the superior browser in all other respects. Thank you.
Opera needs a confirm exit dialogue.

Every other browser either has this feature built in, or it can be rigged up with an extension. The chrome extensions that can be added after the transferable extension (https://addons.opera.com/en/extensions/details/install-chrome-extensions/) do not work.

Apparently, Mac users have this option: http://help.opera.com/Mac/12.00/en/exit.html

If other browsers can do it, and if your own browser for Apple can do it, I do not understand why you cannot do this for Windows users. This is literally the only thing keeping me from using Opera as a default browser, in all other respects this is the best browser I've used.
It is such a basic, but vital, function. If there is some reason it cannot be done, please explain it.

Opera moderators: Please do not delete this post again . Like I say later, if this cannot be done, just explain why and the matter will be closed. You are the superior browser in all other respects. Thank you.

@leocg A missing feature is not a bug... well at least you're acknowleding that it is MISSING. Users have been asking for this feature for years. Other browsers have it, there is no reason for opera to not have it as well, and NO reason they can't add it to newer versions.
