I've asked this question before. Have not received an answer. I searched the forum and have not found a solution. When I shut down my computer every night and restart it in the morning, Firefox does NOT restore my session. "Restore previous session" is not available. One individual mentioned "virtual desktop". I don't know what that is, don't have one that I know, and don't really need one. SO, can someone please help me so that my session, open tabs, are restored upon Firefox startup? I would greatly appreciate it.
