I closed my previous session and my internet was disconnected. I accidentally open a hyperlink to a site with the Firefox browser while my internet wasn't connected and when my internet finally came back on, my entire session with 50+ tabs of multiple windows were gone, and the restore session button is gone. my browser history is still intact, so is there anyway to restore my browser to a previous day to bring up my browser windows on the previous day? Or do I have to contact customer support for Firefox?
