I still bookmark websites, but only using Firefox's native bookmarks, not on external sites. I have tried using start.me for bookmarking, but it's kind of uncomfortable compared to just tapping the browser's "star" button and have it synchronized between my two (three? Firefox on windows acts as a different device than Firefox on Linux; makes sense since none of them can access data from the other) devices. I have tried making my own bookmark site, but failed. I often have a WhatsApp group, Telegram chat or Discord channel, where I drop all the links.
