Firefox > Set up sync > create an account - this screen tells me my username/email is already in use. i have reset the password but now need my recovery key. I have no idea what this is as i do not remember setting up an account in the past.

hello aaronmcl4, go to firefox > sync > setup sync > i have an account > i don't have the device with me, fill in your account name and password and click on "i have lost my other device" in order to initiate a reset of the recovery key.
