Well, it could be due to a number of reasons. Molly is very traditional in her views. Harry, having had a different upbringing and experiences, may not always agree with her. Her constant interference in his life, whether it's about his career choices or personal relationships, can build up and eventually lead to him snapping. Also, in the context of fanfiction, new and different plotlines can be created where Molly's actions or words cross a line for Harry that causes him to lose his temper.
In fanfiction, Harry might snap at Molly because of her over - protectiveness. She often treats Harry like one of her own children, which can be suffocating for him. For example, she might be overly critical of his relationship with Ginny or his decisions regarding his future in the wizarding world.
There are several factors. Firstly, Molly's motherly nature can sometimes turn into overbearing behavior. Harry, who has his own mind and has faced many challenges independently, may not take kindly to being constantly told what to do. Secondly, there could be a clash of values. Harry may have different ideas about loyalty, friendship, or family compared to Molly. In some fanfictions, political or magical events can also play a role. For instance, if Molly takes a stance on an issue that Harry feels strongly against, it could lead to him snapping at her.
