More heavily than ever, I have every bookmark in my bookmarks toolbar, all in folders such as 'home' and 'work' for local URLs, 'checkout' for things I've found but not researched, 'git' for URLs to my GitLab / GitHub projects etc... pretty much every fancy bookmark management service or replacement has massively disappointed me, overly complicated or requires running background services (like xmarks) etc... the only reliable one is the built in Firefox sync, then I use a plugin to export bookmarks to HTML on quit which exports to a directory in my Dropbox directory.
