Yes, because it's the only way I can save my phone bookmarks and share it directly with my computer. As a device that I carry with me almost all of the time, there are a lot of sites, articles and etc. that sometimes can't finish to read or explore when on the street or in a meeting with friends or whatever, so I just bookmark them to revisit it later at home from my laptop. Would prefer to export them to a file to avoid the use of a Mozilla account, but it's not possible on Android. At least not that I know of.
