Hi, I'm trying to disable the "restore previous session including tabs" after crash feature. I've disabled the "Restore previous session" check from the general configuration panel. I've changed the following values from the about:config panel: browser.sessionstore.max_resumed_crashes = 0 browser.sessionstore.resume_from_crash = false However after a restart or shutdown, Firefox still shows up the tabs from the previous session. I'm using Ubuntu 18.04 OS. Could someone please help me with this? Perhaps this feature is useful for some people, but for me it's extremely annoying; plus I really like Firefox and don't wanna change browsers. Thanks!
