A person's bookmarks accumulated over many years can amount to privacy sensitive information. I was recently surprised to learn that Firefox's URL bar not only autosuggests stored bookmarked URLs as you type but also speculatively pre-connects them [1]. Can be disabled in `about:config` at `browser.urlbar.speculativeConnect.enabled`, at least in Firefox for Windows. If you save many bookmarks for a long time you may not want nor expect your browser to years later pre-connect to whatever URL or bookmark name happens to match some characters you type! I disabled it. Privacy benefit at a small speed cost.
