Ever since FF/Mozilla/SeaMonkey did away HTML versions of bookmarks, I have always kept autoExportHTML set to true in my user.js file. (Yeah Im showing my age). I love using the HTML version of bookmarks, but it's so ... flat. Id like be able reference a CSS file, local to the profile, and right now I have a script to edit the latest version of bookmarks.html to bypass the Content-Security-Policy meta tag and inject a <link href> to bookmarks.css. Could an exception be made to allow a localized CSS file?
