This article has two objectives. The first objective is to utilize Darbo's fixed-point theorem ($ \mathbf{\mathcal{FPT}} $) and the measure of noncompactness ($ \mathbf{\mathcal{MNC}} $) technique to study the well-posedness (i.e., the existence and the uniqueness in addition to continuous dependence on the data) of a generalized fractional quadratic integral equation in Orlicz spaces $ L_\psi $. Our second objective is to prove and explain the novel properties of $ g $-fractional operators, such as boundedness, continuity, acting, and monotonicity within $ L_\psi $. As a result of our work, several fractional operators are generalized, unified, and extended, including Riemann-Liouville, Hadamard, and Erdélyi-Kober, as well as related classical and quadratic fractional problems. Our theories are supported by several examples.
