Hey, sorry for the late reply, I was off for a while during the lunar new year =)
You can go to the settings ( icon on the top right corner), and Import/Export then export accounts, you will get a .kc file
Then in your other computer, dl the extension, use the same password (it will be used for decrypting the account keys) and choose Import keys, select the .kc file.
Hope this (still) helps!
