Please update the copy and toggle for the setting that currently reads "Sync over metered connections" The default behavior for this setting is "Always sync unless otherwise instructed by the user" but we are changing the language and the appearance of the toggle. Now, the label should be "Sync only over Wi-Fi" and the copy below should read "Prevent Firefox from syncing over a cellular or metered network" The toggle button should be in the Off state by default.

You should never hard code Firefox in strings. Either we back this out, or you fix it very quickly without changing the ID again.

Fixed in Bug 1405430.

Verified as fixed in build 58.0a1 (10-13); Device: Huawei P9 Lite(Android 6.0). The label is "Sync only over Wi-Fi", Off by default and below "Prevent Firefox from syncing over a cellular or metered network".
