Hello Moz and extension developers,

We have a need to override the locale applied to my extension after it
is loaded depending on certain test condition. And here is the bigger
problem. That locale might not be in sync with the the browser locale.
In other words, can I tell moz to use this locale for my extension?
Any ideas would be highly appreciated.

The simple workaround is to update the mapping in chrome.manifest
after the locale is known, but that is kind of ugly, hackish and also
not very useful, since I only know the locale after the extension is
