wooooo hooo !!!! it works

Mostly works. Has a bug where the closing the last tab in the first firefox window closes all of the windows.

Does exactly what it says will do. Awesome.

Awesome! I have been wanting this for a while. It really bugged me that when I closed the last tab, when I reopened it it came back to that tab. I want to save my last session history, but I don't want that to happen if I close all of my tabs. Thanks for solving this annoyance.

This add-on literally makes no sense at all. Firefox ALREADY behaves like this for ages. I was looking for an extension which does the opposite, disables this browser closing idiocy when you close the last tab. So I can sync the add-on via Firefox Sync so I don't have to manually switch browser.tabs.closeWindowWithLastTab to FALSE every time I reinstall browser...

If you can make the opposite of this, then you get instant 5 stars. But for this one, it's gonna remain one...
