How come sometimes Firefox asks to restore a session and sometimes it just decides to restore a session?
After a Firefox crash (which is happening more and more now) there are times when Firefox asks if you want it to restore the previous session, and there are times when it just restores the previous session without asking. If it is a bad website that caused the crash, why do I want Firefox to go back to it?

It asks if you close Firefox normally. If Firefox closes unexpectedly or if you choose to restart the browser after applying an update or installing an extension, then it'll just give you all your tabs back right away.
You can set the pref browser.sessionstore.max_resumed_crashes to 0 on the about:config page to get the about:sessionrestore page immediately with the first restart after a crash has occurred or the Task Manager was used to close Firefox.
See https://wiki.mozilla.org/Session_Restore#Preferences http://kb.mozillazine.org/Browser.sessionstore.max_resumed_crashes

If you see a warning then you can confirm that you want to access that page.
