I delete the name on purpose so I can utilize the horizontal space the bookmarks bar provides more effectively. I name the bookmarks that are not directly on the bar but live in other folders. However I would still not want to lose that bit of metadata. Icons hint at what site the resource is from at a glance.

Makes sense, I don't use the bookmarks bar because I try and keep the UI to a minimum.

yeah, mozilla do need to do some work on the "narrow screen experience" on desktop. Too many builtin things that take up space around the url bar and can't be moved.
