Years (and years) ago, there was PowerMarks by Kaylon. It was great. Cross-browser, pretty good automated, over-rideable indexing -- space-separated words/symbols, very quick to maintain, with fuzzy matching. Rapid, "instantaneous", incremental search against thousands of bookmarks. It's gone, now, and I've never seen its equivalent. These days, I use an extension that saves a local copy of the page. As others have mentioned: Linkrot. But it's not nearly as quick or convenient to return to a page as it was in PowerMarks. Although, the extension I use does have search -- manually triggered, and thereupon taking some time to initially build the index. But I end up saving more "read later" stuff in it, as opposed to just reference links. So it ends up being a bit noisier, and size means I end up with multiple stores having multiple indexes.
