So I was borrowing a friend's laptop and signed into Chrome with my Google account and synced everything up on that laptop so I could use my saved bookmarks and other settings during the time I was borrowing it. I forgot to log out of it and somehow, I found on my personal laptop all of their bookmarks that they've had for ages overwrote all my bookmarks on my google account. I have no idea what they did (they don't remember or know how either). Is there any way to recover or revert back the bookmarks that I originally had?
