Force stop Chrome Android

Welcome to Android Central! Sorry that you feel that way. I think it's a little unfair to characterize Android as being for "condescending programmers," but I can see how it can be frustrating to someone who isn't used to it. Everything has a learning curve, and Android's is admittedly a little steeper than iOS's, but I think the benefit is much more choice and flexibility. For example, if your sister was frustrated by how Chrome was behaving, she could have easily tried any number of other browsers available in Google Play, like Dolphin Browser, Boat Browser, Maxthon, and Opera, to name just a few. Maybe if she picks the device up again in the near future, you could suggest those options for her.

By the way, I would suspect that the reason why your sister had all of those spawned windows was the website she visited, rather than Chrome itself. Travel and vacation sites are notorious for popups and multiple windows, especially if you initiate a search. But I would agree that once there are a lot of tabs open, it can be tedious to close all of them individually in Chrome, since the "X" tab close button is small, and is right next to where you press for a new tab.
