I've been using XMarks for a decade, but just received a notification from LastPass that as of May 1, they're discontinuing the service. I'm a web developer, and I rely on bookmarks being synced between devices and browsers.
I know that Chrome and Firefox each have their own syncing service across devices, but I need a service that will sync one set of bookmarks across all browsers on all devices.
I'm not a fan of del.icio.us, or any social service. Are there any alternatives? I'm fine with having to install a plugin on all my browsers and devices.
ETA that I want something that will sync my current bookmark bar folders (i.e. enhance the native browser bookmarks, not redesign the bookmark experience). I do not want a "manager" that requires me to open a separate app, or go to a website, to access my bookmarks.
