Ways to tell them apart:
Rightfully often carries a sense of entitlement or legal/ethical correctness, like having a right to something.
Rightly is used more in the sense of moral or logical correctness, often implying an opinion or judgment that is correct.
To remember the difference, associate rightfully with right as in legal rights, and rightly with right as in correct or proper reasoning.
Think of rightfully where you might use justly regarding ownership or claims, and rightly where you might use correctly relating to opinions or evaluations.
Consider rightfully as stronger and more official, while rightly has a more personal opinion or judgment feel to it.
