I have been doing my bookmarking with Pinboard.in which also happens to have a "Read It Later" feature that I've been using now after I stopped using Pocket and Firefox few months ago (stopped using them together). It works really great. On OSX I use Shiori app (for both bookmarking and RIL) and on Android I use Pindroid (a 3rd party app) that adds two options "bookmark" and "read it later" options in Android's "share" pick menu.

However I must say their official browser extensions leave a lot to be desired and that honestly is sad.
