I don't think so. Hillary still blames Comey for losing the election
Yes, all reasonable people are agreed that but for Comey's actions, Clinton would likely have won the election. But does that mean she would have willingly handed the Republicans the excuse to impeach her for obstruction of justice by firing Comey right off the bat? I don't think so. I think she would have tolerated the guy's antics, the same way Obama did for so long, unless he did something so obvious and egregious that she was certain even the Republicans would feel vulnerable holding it against her for firing him.
As for Clinton's insightful analysis of what happened in the election, I think she does a good job identifying many of the reasons she lost... including ample time blaming herself. My only problem with it is she goes overboard in that direction. As a woman, I'm keenly aware of the tendency for female professionals to over-apologize. There's even professional training to help women identify this self-flagellating (and self-defeating) tendency, in order to fight against it. It's been widely commented on:

Clinton certainly fell into that trap after the election, when she became the only presidential candidate in history to apologize for losing. Few candidates have ever fought as hard as she did and endured as much. She worked herself so hard she literally collapsed at one point. And for months she went toe to toe with Trump (including kicking his ass in the debates), even as he whipped up crazed crowds in chants of "lock her up." And yet despite all she did and endured, she felt the need to apologize to her supporters, and then to spend a big chunk of her book beating the crap out of herself for all the moves she could identify as errors with 20-20 hindsight. You just don't see that with defeated male politicians, who pat themselves on the back for fighting the good fight and move on. With Clinton being such a well-respected woman and such a feminist icon, I wish she could have avoided that trap of being overly apologetic, since it would have made her a good role model.
