I'm going to split this work into four parts: 1) Migrate FxA refactor 2) Consolidate ValueSelector 3) Final bunch of mozL10n.get removals 4) This bug which will basically move l10n.js to l20n.js and update API calls

Alberto, I'm done with porting TV System to be ready for L20n. The remaining piece is bug 1246588. Once this is done, I'll switch TV System and then both systems will use L20n. Am I correct to assume that bug 1246588 is on you?

It seems that the merge is not finally happening (let's talk offline about it) so I'm not sure what the next steps are.

Ok, in the meantime, I filed bug 1252936 so that I can port just the L10n/I18n portion of the changes and unblock moving smart-system to l20n.

Most of the transition is automatic: 1) navigator.mozL10n.* -> document.l10n.* 2) navigator.mozL10n.once -> document.l10n.ready.then In a few places I removed the mozL10n.once wrapper because it's not needed anymore (whole L10n is asynchronous and doesn't have to wait for anything). In one place - net_error.html - I left l10n.js because it requires all l10n resources to be loaded locally and l20n.js doesn't support that yet. That's also what we did for ./apps/system and I filed bug 1247096 to tackle that separately.

Cool! Thanks! That concludes the whole moving TV to L20n story! :) Commit: https://github.com/mozilla-b2g/gaia/commit/6e176e0584fdb0dcc59b041ecc2a38aaf2477996
