I use a self hosted book manager. To be honest it is effectively write only memory. I assume it is still being written to the DB, but browsing them has been broken for a long time. I assume that I can fix this if I really need to find a bookmark, but so far it has been a few years. Yet, if I don't bookmark it, I just have a terrible time letting go of tabs that I think I'd like to follow up on some month/year in the future.
