Thank you! I used ublock origin to add this which seems to work well for my tastes:

    news.ycombinator.com##.comment:style(max-width: 60ch !important; overflow: hidden !important;)

EDIT: I felt that the comment header needed to be increased in visibility so I added this:

    news.ycombinator.com##.comhead:style(background: #e6e6df; font-weight: italic; color: #686868 !important;)
    news.ycombinator.com##.hnuser:style(background: #e6e6df; font-style: italic; color: #575757 !important;)

)

Note: ublock origin needs to be enabled for these rules to take effect.
