Did Firefox already add AI into Tabs? Today I just got my first 'Tab Grouping' and it says "Nightly uses AI to read your Open Tabs". That's the worst way to do grouping ever... just group hierarchically based on where it opened from...
Particularly since they clearly keep this info around - if you install TreeStyleTabs or Sideberry, you'll see it immediately show the historical-structure of your current tabs (in-process at least, I'm not 100% sure about after kill->restore). That info has to come from somewhere.
