Changing of addresses within Jaxx Liberty is normal and part of our safety features.
Jaxx Liberty is an HD (hierarchical deterministic) wallet, which means it generates a new address every time you receive digital assets to your Jaxx Liberty wallets as a way of keeping your balance private.
You can see all of the addresses generated by Jaxx Liberty in MENU > Tools > Display Private Keys > ☑It’s safe> View Private Keys > Select a coin/token
You can use any of the previously generated addresses to receive digital assets anytime and without any issue.
PS. We have disabled HD for Ethereum (ETH), Ethereum Classic (ETC) and RKS (RBTC) as the genesis address is only utilized to keep tokens in one address.
