I was trying to sync a 3rd computer and when I looked up what I thought was the current sync key and entered it, I realized the key I used was old and now doesn't match the other 2 computers. How can I delete the wrong key from the 3rd computer in order to enter the correct key?

hello, on your 3rd computer go into Firefox > options > sync and click on "unlink this device" afterwards you can set it up again with the correct credentials.
