Why Bookmarks?

Today, everyone uses more than one device, more than one browser, and/or more than one operating system. We use desktops, laptops, tablets/iPads, and mobile phones; we use Chrome, FireFox, Safari, Edge, Opera, Brave, etc.; we use Windows, MacOS, Android, iOS, etc. Not only that, some people use “virtual machines.” Add to this the fact that transferring bookmarks from an old device to a new one can be a nightmare … or, we might not remember doing so before getting rid of the old device! So, with all these hardware and software technologies, wouldn't it be good to have all our bookmarks easily available and synchronized everywhere?
