This addon is not availabe on my mobil phone / tablet using firefox for android.

Edit:
Thanks for the fast reply. I can live with that

The sync-Mechanism works completely different on Android devices. I don't even know, if it would be possible to implement an additional sync-engine as an add-on.
So for now, there are no plans to implement this, sorry.
