I use Facebook on my phone by browsing their mobile website. I also use a separate browser (or browser profile) for Facebook both on mobile devices and desktop devices, to remove any linkage between my regular browsing and Facebook activities. Further, I run a connection blocker such as uBlock where applicable, to only allow access to first-party resources and 3rd-party resources only when whitelisted.<p>Facebook is useful but not on their terms rather than mine.
