Closing the browser automatically closing all the tabs

more options

When I click the close browser button all my tabs closing at once without any notification. I remember that in old versions of FF there was an option in preferences about notification before the close. Now it has gone.

I know about about:config and browser.tabs.warnOnClose, browser.tabs.warnOnCloseOtherTabs; set on true.

So what is the problem?

Hello d.y.korolkov,

Would you check this setting please :

3-bar menu (or Tools) => Options => General

Under "Startup" : make sure that "Restore previous session" is unchecked.

If that box is checked, you won't get that warning .....

Thanks a lot! Very strange decision from FF UX team! I really like to restore the session when occasionally my FF process has been closed, but from other side I don't like when occasionally push top right cross and every site is closing. This should be different options I guess.
