Reviews saying this syncs through Firefox are incorrect - this syncs ONLY through Dropbox. Useless to me, I'll just make a "Read Next" bookmarks folder, FF will sync it for me to all my devices. No need to add yet another extension and slow my browsing to a crawl.

Blows the competition away. This is a really lovely looking app and the "add to read next" icon on the toolbar is really in-keeping with Firefox's own icons, and the reading list side-bar is nice and compact. Nice one!

Great extension! All that you need for reading list, besides one thing... It's great to have the sync though FF bookmarks. This will allow to sync reading list with FF on my phone.
