Let \( F_{1} \) and \( F_{2} \) be the left and right foci of the ellipse \( \frac{x^{2}}{a^{2}}+\frac{y^{2}}{b^{2}}=1 \) where \( a > b > 0 \). There exist points \( A \) and \( B \) on the ellipse such that \( \overrightarrow{F_{1} A} = 3 \overrightarrow{F_{2} B} \). Determine the range of the eccentricity of the ellipse.
