Why isn’t VS Code setting every line to a max of 80 on save?

I installed the Prettier extension and the max line width is set to 80. I also have it set to format on save. When I save the file I’m working on, I see that the comments are still really long widths. The extension should be shortening these to 80 max width, but it’s not doing it. Is there another setting I need to use? Or maybe there’s a better extension than Prettier? I just want to use whatever formatter that will get rid of the 200+ errors when I try to deploy my typescript cloud functions.
