Steps to reproduce:

In my country Monday is considered the first day of the week and I have set this in the Lightning settings. This works fine and the week view displays the week from Monday to Sunday.

But each time the Lightning Add-On is updated, the first day of the week is reset to Sunday. 

Actual results:

After the update the week view displays the week from Sunday to Saturday and the Thunderbird Lightning settings UI reports Sunday as the first day of the week.

Expected results:

The preference of that setting should also be transferred when the Add-On is updated.

What localization are you using? Is this also fitting to your location? On what OS are you? If on Linux, do you install from package manager or from Mozilla website / in product update?

I use the German Version of Thunderbird and I'm located in Germany.
Thunderbird 38.4.0 with Lightning on Win7/x64. Normal update with the internal Thunderbird Add-On-Update mechanism.

Thanks. I can confrim this.

Other than the bundled builds, the AMO builds don't seem to ship localized default prefs with an lightning-l10n.js. So, this may lead to reset the prefs.

Phillip, any thoughts on this?

See Bug 395504.

A workaround might be to create a user.js (http://kb.mozillazine.org/user.js_file) with the first day setting in it.

I think we should fix bug 395504 instead. I could imagine doing so by using nsIPrefService::readUserPrefs on lightning-l10n.js of the currently loaded locale, given that doesn't overwrite user.js and custom set preferences.

I don't get it: why is this pref overriden every time Thunderbird updates Lightning while other prefs are not? It's painful to have to fix the first day of the week after each update.
