You can try out this extension -> https://addons.mozilla.org/firefox/addon/reading_list/

@ TyDraniu this extension is nice, but It can't provide syncing between desktop and mobile devices, which is what many people are yearning for... Just make it optional to reenable reading list on Firefox desktop, it really should not be that complicated. I won't install Pocket on my mobile devices because I don't like it.

Currently, this is an iOS-only feature, and it does not sync.

What is the benefit of Reading List vs. Bookmarks?

Mozilla recently started up a new "Ideas" site at https://connect.mozilla.org/. I think if you have time, it would be a good idea to post there to get into the current feedback stream.
