For es-MX - if it's the es-CL folder. For FFx-iOS_AppStore-iPadPro_es-CL_Fast-Phone-Website.png, I would say "usuarios de Firefox" instead of "usuarios Firefox" For FFx-iOS_AppStore-iPadPro_es-CL_Sync.png the first part of the description should read "Accede los marcadores, el historial" (so take the "a" out and add a comma where there is an extra space"). Everything else looks great! File location: https://app.box.com/s/1x7n8q0od9kgbzxnbcky78ohnf95024r
One more thing for - FFx-iOS_AppStore-iPadPro_es-CL_Fast-Phone-Website.png In the actual iPad image it says "Añade" but we typically use "Agrega" for es-MX.
Fast-Phone-Website and Sync screens updated for review: https://app.box.com/s/d28h7avguxfxajnql5npobejs41hgcao All screens renamed as MX!
Thanks for the review and approval. Mark it as fixed now.
Note: Exported assets from previous upload had some extra white space. They have now been revised to correct size: https://app.box.com/s/d28h7avguxfxajnql5npobejs41hgcao
