It's a shame that Firefox Android still hasn't got its shit together wrt add-ons. The current selection is abysmal. It would be nice to have the same addon setup on desktop and mobile and have settings sync across devices.
You can create a collection on AMO and set that instead of the whitelist. It's been enabled on Firefox Nightly since october.
It does happen to break some addons, e.g. Greasemonkey, but most work just fine.
