I saw someone recommend Memex as a Firefox extension for full-text search in history and bookmarks the other day. I've started using it, but can't yet comment on its usefulness. It stills feels a bit complex to share data between my computers (I wish for p2p, Nextcloud support, or something alike). I don't like too much it moving DDG's instant answers to the bottom of the page, nor the default sidebar and highlighter, but that could just take some time getting used to.
