Let $\kappa$ be the extinction moment of a critical branching process in random environment with linear-fractional generating functions $f_n(s)$ of the number of particles in the $n$th generation, $n=1,2,\dots$ We give conditions on the parameters of $f_n(s)$ under which $$ \mathsf P\{\kappa=n\}\sim cn^{-3/2}, $$ as $n\to\infty$, where $c$ is a positive constant.
