My dad has his browser full of open tabs that he refuse to close, he has Firefox set to reopen all tabs on restart.

This is due to him wanting to preserve the tab history and context.

He has done this for at least a decade or so....

I even had to help him migrate the open tabs from his old computer to his new.

Bookmarks doesn't preserve the history of bookmarks so he doesn't want to use them....

Best thing after "Those people who enjoy your memes, are they in the room with us now?" - therapist session.
