- save and quit
     - quit (without saving the session)
     - cancel

You all may have read at least one time something about the session restore on closing or something known as the old "showQuitWarning" in the about config. I'm not here to submit again this issue, but I would like to let you know that a lot of users worldwide are still experiencing the lack of this old feature... here you can see an example from the [https://forum.mozillaitalia.org/index.php?topic=71396.15 mozilla italian support forum] ... and there are many more. For completeness, i'll quickly resume the issue: in the previous versions of firefox, enabling the "showQuitWarning" label in the about:config menu used to produce the following behaviour: -> when closing firefox with more than one tab open a confirmation box appeared showing 3 options: - save and quit - quit (without saving the session) - cancel at the reopening of firefox, based on user settings, if it was chosen the "save and quit" option then the previous session used to be restored otherwise a new session would have been created. To date, there are a lot of configuration to play with regarding session, closing and similar, but nothing covers some use cases that were perfectly covered by the old method, for example: -> the sessions are now always saved, even when the user doesn't want to, even when that session is just useless ->if you set the automatic session restore at each startup then you will have to manually close all the tabs open from the previous session even if you didn't mean to save them, or manually start a new session ->if you don't set the automatic session restore then at the startup you have to remember to manually reopen previous session, if you forget that, or for example your antivirus or an html file you click on, opens your browser and you instinctively close it then next time you open the browser you realize you've lost the session you had to manually restore. So, please, before archiving this topic, do your own research on this subject and try to understand that could be something important. Let's make this community intercept users needs and show what a community means (that was the key aspect of the golden years of firefox)... let's prevent together other migrations to chrome or the new edge.
