Chrome is supposed to tie them with the single instance you're running. You can't just copy the Chrome folder and transfer it to another location. You'd have to use Chrome's Sync for that. I'm assuming Chrome has been opened at the same time by the OP, allowing Opera to snatch the passwords and other shit, making an intrusion into Chrome's data.

But, on the other hand, I was able to copy the data from a Chrome extension after a system crash on one machine and extract the data to a new machine just fine by reinstalling the extension and then pasting the extension's folder to the same location where it was on the previous machine.

Since that extension was Mailvelope, I would essentially lose a private key in this case if that wasn't possible, since I didn't have the backup of it. Not sure if I would call that bug or a feature.
