Yesterday I clicked my Firefox's red X (top left), this immediately closed my Firefox window, yet the process was still running (Due to the glow under the Firefox icon in the Dock). Is there some way to re-open Firefox with all the tabs it had? (If I open Firefox again, it loads without past tabs...) I have an add-on called Session Manager which indeed saves my tabs, but only if I go to Menu Bar: Firefox > Quit Firefox. If I click the red X it won't remember my tabs at all. So, any way to disable the red X? If not, then I'll just have to be careful when minimizing the window.
