What I don't like about Firefox is the fact that it will load all the tabs and windows you had opened before shuting down the computer and there is not a clean way to make it stop. When I finish my day, I like to shutdown the computer and go to sleep or whatever and every day when I open Firefox, all the windows will reopen and I need to close it and re-start... I just want to be able to disable this behaviour from the settings, but it looks Firefox just don't want to address this

The "Restore previous session" checkbox is the first setting in the preferences for me (wording may differ a little as I'm not on the English version though). Doesn't that work for you?

Does "Restore previous session", literally the first setting not work? Firefox will reopen my tabs only if my computer doesn't cleanly shut down or I don't close it before shutting my computer down.

This doesn't directly address your problem, but I use the Total Suspender extension and it keep all the tabs from reloading when FF starts up.

by default, on a fresh I install, Firefox dont saves the tabs. You would enabled it.

While session restore of your tabs is off by default in Forex, I believe shutting down your computer while Firefoxis running is a special case. Since the user didn’t explicitly quit Firefox, it is trying to resume where you left off.
