The firefox integration is not a pocket-brand application, website, or technology. It uses pocket's public API and is open-source, mozilla-developed and -licensed code.
I thought the API used was undocumented and custom to Firefox? I don't know where exactly I found the Google groups discussion going on between various Mozilla people and the community, but this was a point made a number of times. IIRC at least one Mozilla person was working on getting clarification regarding this clause of the TOS.
The part where you log in and then explicitly upload specific URLs to Pocket? The part where you navigate to the Pocket app and use it? This sounds like any other website.
