We need to support Firefox 13 for both desktop and mobile asap. It's going to be a big release - lots of work to do. I don't think we should drop Firefox 10 from the UI yet. Still getting about 12% of visits from Firefox 10. FYI, Firefox 10 is the only current mobile version. Adding support for Fx 13 would then give us two mobile versions - 10 and 13.
Firefox 10 is ESR, not sure our support story there but that's something to keep in mind.
As of the planning meeting happening right now, we won't need m13 support. Native UI will be Firefox 14 and everything will be merged on Aurora 14 with everyone else. We'll probably want to support m14 very soon (sooner than desktop). I'll talk to Michelle about that.
Want me to go ahead and add fx13 and m14 then?
yes, please add m14. thanks!
Landed fx13 and m14 in prod. https://github.com/mozilla/kitsune/commit/d89c075969325d5da42a6ac4a545921b5cebc37e
