So, I'm in a bit of a panic... after downloading and installing 11.1 my MacBook Pro restarted and all of my Safari tabs and windows were gone. I thought it was no big deal and that I could click "Reopen all windows from last session"... wrong. It was grayed out, along with "Reopen last closed window). I restarted the Mac again, and no luck. I have no Time Machine backup, and I hoarded dozens of important tabs... I guess maybe I'm screwed unless anyone knows any tips I could try.
