The Chinese version of Firefox has the ability to switch between in country and global sync servers. We should provide this same functionality, most likely controlled by a preference. https://github.com/MozillaOnline/gecko-dev/commit/4fcd7086e0322143ed097c6eefb9b4a450b98f4b

Afaik this can already be done - Is this bug about adding a UI option for that?

> Afaik this can already be done - Is this bug about adding a UI option for that? Yes. I remember an explanation of they "why" of the sync server situation in China, but I can't find that right now. I guess when you are inside China, in most places you can't use our global sync servers.

There's some discussion about this in Bug 1227843. There's only one iOS app, so it includes the Chinese customizations.

Could we implement this similar to how it was done in iOS?

This patch would be dependendent on a distribution preferences file that looks like this one.
