Hiya I want to be warned when quitting multiple tabs BUT I do not want the session restored when opening again. This used to be possible but now in Settings if I untick Restore previous session even though Warn you when quitting the browser is ticked it does not give a warning when I quit Firefox. So this means if its unticked then if I accidently hit the close button I loose all the open tabs in firefox. If ticked I have to close all the tabs manually each time I close firefox to prevent thm opening when I start Firefox again. Im on Windows 10 Pro 21H1 with Firefox 93.0 any idea if I can change this behaviour in the advanced prefs? (about:config) thanks for any insights A

Type about:config<enter> in the address bar. If a warning screen comes up, press the I Accept the Risk button. At the top of the screen is a search bar.

browser.tabs.warnOnClose = true

browser.tabs.warnOnCloseOtherTabs = true
